TABLE NOTATIONS

* With the protective system trip breakers in the closed position, the CEA drive system capable of CEA withdrawal, and fuel in the reactor vessel.

# The provisions of Specification 3.0.4 are not applicable.

(a) Trip may be manually bypassed above 10*% of RATED THERMAL POWER; bypass shall be automatically removed when THERMAL POWER is less than or equal to 10*% of RATED THERMAL POWER.

(b) Trip may be manually bypassed below 400 psia (28.1 kg/cm3A) ; bypass shall be automatically removed whenever pressurizer pressure is greater than or equal to 500 psia (35.2 kg/cm2A).

(c) Trip may be manually bypassed below 10"*% of RATED THERMAL POWER; bypass shall be automatically removed when THERMAL POWER is greater than or equal to 10"*% of RATED THERMAL POWER,

(d) Trip may be bypassed during testing pursuant to Special Test Exception 3.10.3.

(c) See Special Test Exception 3.10.2.

(f) There are four channels, each of which is comprised of one of the four reactor trip breakers, arranged in a selective two-out-of-four configuration (i.e., one-out-of-two taken twice).

(g) There are two channels, each of which opens one Control Element Drive Mechanism Motor Generator output contactor arranged in a two-out-of-two logic, thus removing motive power to the Reactor Trip Switchgear System.

ACTION STATEMENTS

ACTION 1 - With the number of channels OPERABLE one less than required by the Minimum Channels OPERABLE requirement, restore the inoperable channel to OPERABLE status within 48 hours or be in at least HOT STANDBY within the next 6 hours and/or open the protective system trip breakers.

ACTION 2 -

TABLE 3.3-1 (Sh. 5 of 8)

ACTION STATEMENTS

With the number of channels OPERABLE one less than the Total Number of Channels, STARTUP and/or POWER OPERATION may continue provided the inoperable channel is placed in the bypassed or tripped condition within 1 hour. If the inoperable channel is bypassed after 7 days, the desirability of maintaining this channel in the bypassed condition shall be reviewed by PNSC within the next 24 hours in accordance with Specification 6.5.1.6.g The channel shall be returned to OPERABLE status no later than during the next COLD SHUTDOWN.

With a channel process measurement circuit that affects multiple functional units inoperable or in test, bypass or trip all associated functional units as listed below:

Process Measurement Circuit

1. Linear Power (Subchannel or Linear)

STARTUP and/or POWER OPERATION may continue until the performance of the next required CHANNEL FUNCTIONAL TEST. Subsequent STARTUP and/or POWER OPERATION may continue if one channel is restored to OPERABLE status and the provisions of ACTION 13 are satisfied.

With the number of OPERABLE channels one less than the Total Number of Channels, restore the inoperable channel to OPERABLE status within 48 hours or be in at least HOT STANDBY within 6 hours and in HOT SHUTDOWN within the following 6 hours.

With the number of OPERABLE channels one less than the Total Number of Channels, be in at least HOT STANDBY within 6 hours and in at least HOT SHUTDOWN within the following 6 hours; however, one channel may be bypassed for up to 1 hour for surveillance testing provided the other channel is OPERABLE.

With the number of OPERABLE channels one less than the Minimum Number of Channels, restore the inoperable channel to OPERABLE status within 48 hours or be in at least HOT STANDBY within the next 6 hours and in COLD SHUTDOWN within the following 30 hours.

With the number of OPERABLE channels one less than the Minimum Number of Channels, operation may continue for up to 6 hours. After 6 hours, operation may continue provided at least one train of essential ventilation is in operation, otherwise, be in HOT STANDBY within the next 6 hours and in COLD SHUTDOWN within the following 30 hours.

With the number of OPERABLE channels one or more less than the Minimum Channels OPERABLE requirement, place affected channel(s) in bypass and restore all channels to OPERABLE status prior to entering MODE 2 following next MODE 5 entry.

(1) Each train or logic channel shall be tested at least every 62 days on a STAGGERED TEST BASIS.

(2) Testing of automatic actuation logic shall include energization/ deenergization of each initiation relay and verification of proper operation of each initiation relay.

(3) A subgroup relay test shall be performed which shall include the energization/deenergization of each subgroup relay and verification of the OPERABILITY of each subgroup relay.

Abstract (15-20 Lines)

The study was performed with the purpose of evaluating the impact of extending STI (surveillance test interval) and AOT (allowed outage time) of the RPS/ESFAS (reactor protection system/engineered safety feature actuation system) in KSNPP (Korean standard nuclear power plant) on plant risk To do these, three measures for plant risk - unavailability, CDF (core damage frequency), and LEAF (large early release frequency) - were basically used. This activity included development of the detailed fault tree models for RPS/ESFAS in KSNPP and the plant-specific CDF and LEAF models. These models formed the basis for the work reported herein. This study focused on evaluating the risk impact of changing current TS (technical specifications) for the RPS/ESFAS of the KSNPP into standard TS (NUREG/CR-1433). The results of the study showed that the current TS for the RPS/ESFAS of the KSNPP might be modified or restructured so as to reduce the burden on plant operation in terms of manpower problem, exposure to test-induced transients, impact on equipment life and unavailability due to test, and so on. The results of the study are applicable to Ulchin units 3 & 4, as well as Yonggwang units 3, 4, 5, and 6.
