B. Importance of Research and Development
As the nuclear power generation continues, the accumulation of spent fuel and its disposal become
an urgent problem and, therefore, each country is developing its own technology for the back-end
fuel cycle. The DUPIC technology has been developed to convert the spent PWR fuel into the
CANDU fuel, which can resolve the accumulation of spent PWR fuel and reduce the spent
CANDU fuel. In order to prove the feasibility of the DUPIC technology, the compatibility analysis
of DUPIC fuel with current CANDU reactors and the economic analysis have been performed
by Korea Atomic Energy Research Institute (KAERI) during Phase I period (1997.7.21 -
2000.3.31).
In order to prove the compatibility of the DUPIC fuel, the reference DUPIC fuel composition
was determined, the performance of the reactor analysis code was assessed, the compatibility
of individual reactor system was analyzed, and the uncertainty due to the fuel composition was
estimated. These studies have demonstrated that the current DUPIC fuel model is compatible
with the current CANDU 6 reactor. This result will be used as a basis for Phase II study, which
focuses on the feasibility of practical use of the DUPIC fuel and the reactor safety analysis.
Once the safety analysis is completed, the DUPIC fuel compatibility analysis will be accomplished.
Based on this, the possibility of licensing and key issues for the practical use of DUPIC fuel
can be discussed.
- Technical Aspect of Research and Development
The reactor physics analysis on the DUPIC fuel core utilizes the existing analysis method but
also requires new methods that can quantitatively estimate the sensitivity of the core performance
parameters to the fuel composition and power distribution. Therefore, it is possible to improve
the current CANDU core analysis technology and acquire a leading technology in CANDU fuel
development by establishing the DUPIC fuel core analysis method.
- Economic/Industrial Aspect of Research and Development
- 14 -
KAERI/RR-1999/99
Until now, the CANDU core design and analysis are partly dependent on the foreign technology.
During the Phase I period, it was possible to develope and localize a part of such technology.
As far as the compatibility analysis is concerned, it is more important to have the technology
that can be used to determine the compatibility of the DUPIC fuel than the compatibility of
the DUPIC fuel itself. It is expected that the localization of technology will contribute to the
import substitute in the future.
- Social/Cultural Aspect of Research and Development
There are diverse technical questions on the feasibility of loading DUPIC fuel in a CANDU
reactor, because the CANDU reactor was originally designed for natural uranium fuel. In order
to resolve those technical uncertainties and to provide a rationale to develope safeguardable
DUPIC technology, the compatibility analysis of the DUPIC fuel should be performed.

IV. Results and Proposal for Applications
A. Results of Research and Development
1) Feasibility analysis on applicability of the current core design method
The major differences between DUPIC and standard CANDU fuel are the fuel bundle
configuration and fuel material composition. The DUPIC fuel bundle adopts 43- element model
which has been developed for natural and slightly enriched uranium (SEU), while the standard
fuel has 37 fuel elements. For the fuel composition, the center rod of DUPIC fuel bundle contains
burnable poison material, while the standard fuel has no poison material. The DUPIC core model
is the same as the standard CANDU 6 reactor model. However, the fuel management method
of the DUPIC core is a 2-bundle shift refueling scheme, while the standard core uses an 8-bundle
shift scheme. For the analysis of the DUPIC fuel system, a transport code WIMS-AECL is
- 16 -
KAERI/RR-1999/99
used for lattice calculations and SHETAN code is used for the reactivity device analysis. Other
computer codes for the core and safety analysis are the same as those used for the standard
core analysis.
The benchmark calculation of the lattice code WIMS-AECL has been performed for the DUPIC
fuel using MCNP code. For the criticality calculation, the eigenvalue (koo) error was within
0.73% 5" k. In general, the error increases as the fuel burnup increases. The void reactivity
estimated by WIMS-AECL matches that of MCNP within 5%. However, the fuel temperature
(Doppler) coefficient has a relatively large error of 80% at the discharge state. The results of
benchmark calculations have shown that the WIMS-AECL is in general acceptable for DUPIC
physics design and analysis. However, for the slow transient that includes the fuel temperature
chang, there is a slight loss of accuracy due to the imperfectness of the temperature data.
The validation calculation of WIMS/SHETAN/RFSP code system, which is used for the DUPIC
core analysis, was performed using Wolsong 2 physics measurement data. The validation
calculation includes the calibration of boron reactivity, adjuster rod worth, shutoff rod worth,
mechanical control absorber worth, temperature coefficients of the coolant and moderator, and
power distribution. The results have shown that the average error of zone controller unit (ZCU)
worth is less 3%, which enhances an error of 0.2% 5" k for criticality. In general, the error of
reactivity device worth is less than the permissible error of 15%. The flux scan error is about
10% which is also less than permissible root-mean-square (RMS) error of 15%. The coolant
temperature coefficient was consistent with the measurement result. The results of validation
calculations have confirmed that the current core analysis system is acceptable for the feasibility
study of the DUPIC fuel compatibility analysis.
2) Feasibility analysis on operation of the DUPIC fuel core
At the initial burnup state, the reactivity coefficients of DUPIC fuel are different from those
of natural uranium fuel For natural uranium, as the fuel burnup increases, the reactivity
coefficients such as the fuel and moderator temperature coefficients increase rapidly because
Pu content increases significantly. On the other hand, the reactivity coefficients of the DUPIC
fuel are not favorable as compared with natural uranium fuel at the initial burnup stage. However,
- 17 -
KAERI/RR-1999/99
the change of the reactivity coefficient is small because Pu content changes little as the fuel
burnup increases. Therefore, the overall behavior of the DUPIC fuel is better than that of natural
uranium fuel at the equilibrium burnup state.
To assess the performance of the operating reactor, the probability to exceed the administrative
limits was estimated based on the result of 600-FPD refueling simulation. For convenience, the
administrative limit was set as 95% of the operation limit. The administrative limits for the
channel and bundle powers are 6935 kW and 888 kW, respectively. The channel power peaking
factor of 1.10 and ZCU level of 0.2-0.8 were chosen as the administrative limits. For the DUPIC
fuel core, the administrative limits of the channel and bundle powers were not exceeded, whereas
the natural uranium core has the probability of 0.3%, which shows there is no significant difference
in the reactor power characteristics between two cores. The probability to exceed the limit of
channel power peaking factor was 0.17% for DUPIC core whereas the natural uranium core
was found to never exceed this limit. For ZCU level, the probability was 0.12% and 0.15%
for the DUPIC and natural uranium cores, respectively. This revealed that both cores are almost
the same in the viewpoint of the operational performance.
The thermal-hydraulic properties were assessed for the time-average cores. The total coolant
flow rate for DUPIC core is 8124 kg/s, which is 2% less than that of natural uranium core.
The maximum channel flow is 26.7 kg/s for the DUPIC core, which is also 2% less than that
of natural uranium core. Therefore the coolant flow rate of DUPIC core meets the design
requirement. The maximum channel pressure drop is 718 kPa at the flow of 23.9 kg/s, which
also meets the design requirement. The minimum critical channel power for DUPIC core is
5148 kW, which is a 3.5% improvement over that of natural uranium core. Therefore it can
be concluded that the thermal-hydraulic performance of DUPIC core is no worse than that of
natural uranium core. The critical channel power ratio is 1.502 and 1.440 for the DUPIC and
natural uranium core, respectively, which satisfy the design requirement of 1.12. The exit quality
of the hottest channel is 3.9% and 3.7% for the DUPIC and natural uranium core, respectively,
which also meet the design requirement of 4.0%. Based on these results, the thermal-hydraulic
characteristics of the DUPIC core are not significantly different from those of natural uranium
core.

3) Compatibility analysis on individual reactor system
For ZCU system, the spatial control capability after refixeling was assessed. The Xe transient
analysis has shown that the power oscillation is controlled for both the DUPIC and natural uranium
cores. For the adjuster system, the functional requirements were confirmed for the power flattening
capability, Xe reactivity compensation during the restart after a shutdown, shim operation during
the malfunctioning of the refueling machine, and reactor power level change. A distinctive feature
of the DUPIC core from the standard core is that the time necessary to reach the full power
is delayed, which is partially due to Xe feedback effect of the DUPIC core. However, the time
delay does not cause any adverse effect on the operation of DUPIC fuel core. For regional
overpower protection (ROP) trip set points, a comparative study has been performed for 232
design base cases. As a result, the ROP trip set point of DUPIC core was found to be 123%,
which is acceptable as compared with 122% for natural uranium core.
For shutdown system 1, the dynamic reactivity is 72.5 mk for DUPIC core, which is large
enough keep the reactor subcriticality. The insertion characteristics of the shutdown rods are
similar to those of natural uranium core. For the assessment of shutdown rod performance, the
reactor inlet header (RIH) 20% loss of coolant accident (LOCA) was analyzed. Though the power
pulse for DUPIC core rises a little earlier as compared with natural uranium core, the overall
integrated thermal energy deposition in the fuel during first 3 sec is almost the same for both
cores. The possibility of fuel disrupture was assessed based on the accumulated thermal energy
during the power pulse. The margin to the fuel rupture criterion, 840 J/g, for DUPIC core decreases
by 3.9% compared with natural uranium core.
For the fuel transportation technology, a transportation cask was conceptually studied, which
contains two spent fuel baskets being used for the dry storage facility at Wolsong nuclear plant.
The transportation capacity is 120 fuel bundles. The overall dimension of the cask is 53.3 cm
in radius, 15 cm in lead shield for photon shielding, and 10 cm in polyethylene for neutron
shielding. The radiation level on the surface and 2 m away from the surface of the cask satisfies
the design requirements of 200 mrem/hr and 10 mrem/hr, when the spent DUPIC fuel cooled
for 10 years is used as the source term. The weight of the cask is —17 ton including the spent
fuel, which can be handled by the head crain of the plant (the maximum capacity of 30 ton).
- 19 -
KAERI/RR-1999/99
The criticality of the transportation cask has no problem.
In the storage pool, the criticality of DUPIC fuel is 0.923 when piled up in the conventional
way. Therefore the subcriticality requirement (0.95) is satisfied. The storage capacity corresponds
to the amount of spent fuel from 12 years operation. In this case the cooling capacity of the
storage pool needs to be increased by 1 MW, considering the decay heat from the spent DUPIC
fuel. "When the cooling system is down, the time for the storage pool to reach 49°C is 10 hours
and, therefore, the cooling system should be restored in that time.
The annual dose of the fresh DUPIC fuel is 6.47 Sv/y for the whole body and, therefore, the
DUPIC fuel should be handled and transported by remote operation. When the DUPIC fuel
is transferred to the plant, they should be located at the loading system by either manual or
remote handling. First of all, the fresh fuel needs to be moved from the storage area to the
loading station (designed for dry storage facility). Once the transportation cask is opened in
the loading station, the basket containing the fuel is taken out and moved to the tilt station.
The fuel basket is moved horizontally to the fuel tray using the tilt station. Therefore, if the
DUPIC fuel transportation cask is compatible with the loading station and the fuel basket is
compatible with the tilt station, there would be no technical problem in handling the fresh DUPIC
fuel.
The compatibility of the fueling machine needs to be considered in two aspects: the endurance
time and thermal capacity. In case of DUPIC fuel, when four channels are refueled everyday
with two fuel bundles loaded in a channel, the endurance time could be reduced by a half.
The heavy water inside the magazine of the refueling machine should meet the normal operating
condition (maximum magazine temperature < 57°C) and design requirement (maximum magazine
temperature < 149°C). This requirement is satisfied if the fueling machine takes fuel bundles
necessary to load two channels at a time. Therefore there is no need to modify the fueling
machine cooling system.
The radiation shielding analysis has shown that the radiation dose outside the primary shield
of the DUPIC fuel core is less than those of natural uranium core except the end shield. Even
for the end shield, the design requirement is satisfied for th DUPIC fuel core. The heat flux
- 20 -
KAERI/RR-1999/99
and temperature requirements for the thermal shield are also met for the DUPIC fuel core.
Radiation damage rate of the critical reactor component was assessed by calculating displacement
per atom (DPA). The analyses have been performed for roll joint, calandria welding area, and
edges/corners of calandria tank assuming 30 years operation, and the results have shown that
the lifetime of the critical component of the DUPIC core could be reduced by 30% compared
with that of natural uranium core.
4) Sensitivity analysis on the fuel composition
Once three inter-assembly mixing operations are taken for 3600 spent PWR fuel assemblies,
there will be 450 distinctive fuel compositions. The distribution of these fuel compositions was
computed with 95% confidence level. In principle, there is no variation in U235 and Pu239
content if the fissile isotopic content is adjusted to the target value. On the other hand, the
standard deviation of fissile content is 2-3% when the reactivity is adjusted to the target value.
The burnup-dependency of nuclear characteristics was assessed through the depletion calculation.
For the fissile content adjustment method, the dispersion of the initial reactivity is relatively
large but it gradually decreases as the fuel burns. However, the trend is reversed for the reactivity
control method. Therefore it can be said that the fissile content adjustment method is more
effective in reducing the DUPIC fuel composition heterogeneity effect than the reactivity
adjustment method.
The uncertainty of the core performance parameter due to the variation of DUPIC fuel composition
has been estimated using a computer code GENOVA which was developed in the course of
this project. The uncertainty of the maximum channel power was obtained based on 600-FPD
refueling simulation. The uncertainty is 1.3% and 7.0% for the fissile content adjustment and
reactivity control method, respectively. To confirm the uncertainty level of the core performance
parameter obtained by the deterministic method and to realistically simulate the composition
heterogeneity on the core performance parameter, a refueling simulation was performed using
30 different DUPIC fuel types. As a result, the uncertainty of the maximum channel power
was confirmed to be less than 1%. Therefore, it can be concluded that the DUPIC fuel composition
heterogeneity does not to impose any serious effect on the reactor operation if the fuel composition
is adjusted.

KAERI/RR-1999/99
5) Economic analysis on DUPIC fuel cycle
In order to estimate DUPIC fuel fabrication cost, a conceptual design of the DUPIC fuel
fabrication facility was performed for the fabrication capacity of 400 MTHE/yr. The levelized
fuel fabrication cost was estimated to be 558 $/kgU. The DUPIC fuel fabrication cost is much
higher than the current light water reactor (LWR) fuel fabrication cost of 275 $/kgU and heavy
water reactor (HWR) fuel fabrication cost of 65 $/kgU, which is due to the fuel fabrication
facility construction cost that requires remote hot cell processes. The effect of using fresh uranium
to control the fuel composition was assessed too. For example, when the slightly enriched and
depleted uranium is added by 6.5% and 10.8%, respectively, the DUPIC fuel fabrication cost
619 $/kgU.
The cost of DUPIC fuel transportation and storage was indirectly estimated based on that of
LWR spent fuel (230 $/kgHM) quoted from OECD/NEA(1993) publication, uisng the decay
heat ratio. As a result, the transportation and storage cost of the DUPIC fuel was found to
be 170 $/kgHM. The DUPIC fuel handling cost was estimated too, which includes the design
modifications to load the DUPIC fuel following the reverse path in the plant. Considering both
the hardware and software modifications, the DUPIC fuel handing cost was estimated to 4500
million Won (reference year 2000), which is then converted to the levelized cost of 5.13 $/kgHM.
The DUPIC fuel disposal facility model utilizes Canadian room-and-pillar design concept. In
order to estimate the appropriate disposal cost, the domestic reactor type strategy was established
at first. Then, the disposal cost was estimated by interpolating the cost data based on the domestic
electricity generation capacity. The levelized cost was calculated by discounting the cost for
the operation period. The disposal costs for the spent LWR1, HWR and DUPIC fuel are 403,
118, and 220 $/kgHM. Considering that the current spent LWR and HWR fuel disposal costs
are 610 and 73 $/kgHM in OECD/NEA publication, the disposal costs estimated in this study
are significantly conservative to be used for the DUPIC fuel cycle cost analysis.
The DUPIC fuel cycle cost was estimated using one-batch model and compared with the direct
disposal fuel cycle. For the estimation of fuel cycle cost, both the deterministic and Monte Carlo
- 22 -
KAERI/RR-1999/99
methods were used. The deterministic analysis has shown that the DUPIC fuel cycle cost is
5.25-5.43 mills/kWh depending on the composition adjustment method while the direct disposal
fuel cycle cost is 5.19-5.24 mills/kWh. However the Monte Carlo simulation has shown that
the standard deviation of the fuel cycle cost is 0.34-0.38 mills/kWh. Therefore, it is believed
that the DUPIC fuel cycle is comparable to the once-through fuel cycle.
B. Proposals for Application
The DUPIC core analysis technology can be used for assessing the compatibility of the advanced
HWR fuel to be developed in the future with the standard CANDU core and for designing
a new HWR core. By developing DUPIC core and compatibility analysis technology, the design
and analysis technology of the standard CANDU core can also be improved. If the accuracy
of the CANDU core design and analysis method is confirmed through the experimental
verification, it is possible to achieve the technology independence for the CANDU core design
and analysis.
The ROP analysis and computer codes developed (fuel management program and perturbation
code) during Phase I of DUPIC project are expected to replace the technology imported for
the HWR core design and analysis. Also the advanced design and analysis method developed
during the course of DUPIC project can be used continuously to the development of advanced
CANDU fuels and could be exported to the developing countries in the future.
Because DUPIC core design and analysis technology includes new analysis methods as well
as the existing methodology, it can be used for the analyses of fuel loading behavior and other
related characteristics, which is necessary to demonstrate the performance of the advanced fuel
being developed. It can also be used for the following research activities;
• Cobalt production in a HWR
• Higher actinide transmutation under high thermal flux
• Thorium fuel cycle.

Abstract (15-20 Lines)
The purpose of this study is to assess the compatibility of DUPIC (Direct Use of Spent PWR Fuelin CANDU Reactors) fuel with the current CANDU 6 reactor, which is one of the technology beingdeveloped to utilize the spent PWR fuel in CANDU reactors. The Phase I study of this projectincludes the feasibility analysis on applicability of the current core design method, the feasibilityanalysis on operation of the DUPIC fuel core, the compatibility analysis on individual reactor system,the sensitivity analysis on the fuel composition, and the economic analysis on DUPIC fuel cycle.The results of the validation calculations have confirmed that the current core analysis system isacceptable for the feasibility study of the DUPIC fuel compatibility analysis. The results of coresimulations have shown that both natural uranium and DUPIC fuel cores are almost the same from_the viewpoint of the operational performance. For individual reactor system including reactivitydevices, the functional requirements of each system are satisfied in general. However, because ofthe pronounced power flattening in the DUPIC core, the radiation damage on the critical componentsincreases, which should be investigated more in the future. The DUPIC fuel composition heterogeneitydoes not to impose any serious effect on the reactor operation if the fuel composition is adjusted.The economics analysis has been performed through conceptual design studies on the DUPIC fuelfabrication, fuel handling in a plant, and spent fuel disposal, which has shown that the DUPIC fuelcycle is comparable to the once-trough fuel cycle considering uncertainties associated with unit costsof the fuel cycle components. The results of Phase I study have shown that it is feasible to usethe DUPIC fuel in CANDU reactors without major changes in hardware. However further studiesare required to confirm the safety of the reactor under accident condition.
