1/4.0' APPLICABILITY BASES If the allowable outage time limits of the ACTION requirements are less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or a shutdown is required to comply with ACTION requirements, e.g.,

Specification 3.0.3, a 24-hour allowance is provided to permit a delay in implementing the ACTION requirements. This provides an adequate time limit to complete Surveillance Requirements that have not been performed. The purpose of this allowance is to permit the completion of a surveillance before a shutdown would be required to comply with ACTION requirements or before other remedial measures would be required that may preclude the completion of a surveillance.

The basis for this allowance. includes consideration for plant conditions, adequate planning, availability of personnel, the time required to perform the surveillance, and the safety significance of the delay in completing the required surveillance. This provision also provides a time limit for the completion of Surveillance Requ.irements that become applicable as a consequence of CONDITION changes imposed by ACTION requirements and for completing Surveillance Requirements that are applicable when an exception to the requirements of Specification 4.0.4 is allowed. If a surveillance is not completed within the 24-hour allowance, the time limits of the ACTION requirements are applicable at that time. When a surveillance is performed within the 24-hour allowance and the Surveillance Requirements are not met, the time limits of the ACTION requirements are applicable at the time that the surveillance is terminated.

l Surveillance Requirements do not have to be performed on inoperable equipment l because the ACTION requirements define the remedial measures that apply. However, the Surveillance Requirements have to be met to demonstrate that inoperable equipment has been restored to OPEPABLE status.

Soecification 4.0.4 establishes the recuirement that all applicable surveillances must be met before entry into an OPERAYIONAL CONDITION or other condition of operation specified in the Applicability statement. The purpose of this specification is to ensure that systam and component OPERABILITY requirements or parameter limits are met before ent"y into an OPERATIONAL CONDITION or other specified condition for which these systems and components ensure safe operation of the facility. This provision applies to changes in OPERATIONAL CONDITIONS or other specified conditions associated with plant shutdown as well as startup.

Under the provisions of this specification, the applicable Surveillance Requirements must be performed within the specified surveillance interval to ensure th'at the Limiting Conditions for Operation are met during initial plant startup dir following a plant outage.

When a shutdown is required to comply with ACTION requirements, the provisions of Specification 4.0.4 do not apply because this would delay placing the f acility in a lower CONDITION of operation.

Soecification 4.0.5 establishes the requirement that inservice inspection of ASME Code Class 1, 2 and 3 components and inservice testing of ASME Code Class 1, 2 and 3 pumps and valves shall be performed in accordance with a periodically updated version of Section XI of the ASME Boiler and Pressure Vessel Code and Addenda as required by 10 CFR 50.55a.

' REACTOR COOLANT SYSTEM RASES .

- 3/4.41 MAIN STEAM LINE ISOLATION VALVES

- Double isolation valves are provided on each of the main steam lines to minimize the potential leakage paths from the containment in case of a line break.

Only one valve in each line is required to maintain the integrity of the containment, however, single failure considerations require that two valves be OPERABLE.- The surveillance requirements are based on the operating history of this type. valve. The maximum closure time has been selected to contain fission products and to ensure the core is not uncovered following line breaks. The minimum closure time is consistent with the assumptions in the safety analyses to prevent pressure ' surges.

3/4.4.8 STRUCTURAL INTEGRITY The inspection programs for ASME Code Class 1, 2, and 3 components ensure that the structural integrity of these components will be maintained at an acceptable level throughout the life of the plant.

Components of the reactor coolant system were designed to provide access to permit inservice inspections in accordance with Section XI of the ASME Botier and Pressure Vessel Code 1971 Edition and Addenda through Winter 1972.

-The inservice inspection program for ASME Code Class 1, 2, and 3 components will be performed-in accordance with-Section-XI of the ASME Boiler and Pressure Vessel Code and applicable addenda as required by 10 CFR 50.55:(;) ::::;t t::: t

3/4.4.9 RESIDUAL HEAT REMOVAL The RHR system is required to remove decay _ heat and sensible heat in order to maintain the temperature of the reactor coolant. RHR shutdown cooling is-comprised of four (4) subsystems which make'two (2 -loops. Each loop consists of two (2) motor driven pumps, a heat exchanger, s and a)sociated piping and . valves. -Both loops have connon suction from the same recirculation loop. Two (2) redundant, manually controlled shutdown cooling subsystems of the RHR System can provide the required decay heat removal capability. Each pump discharges the reactor coolant, after it- has been cooled by circulation through the respective heat exchangers, to the reactor via the associated recirculation loop or to the reactor'via the low pressure coolant injection pathway. The RHR heat exchangers transfer heat to the RHR Service Water System. The RHR shutdown cooling mode is manually controlled.

An 0PERABLE RHR shutdown cooling subsystem consists of an RHR pump, a heat exchanger, valves, piping, instruments,- and controls to ensure an OPERABLE flow path.

In H0T SHUTDOWN condition, the requirement to maintain OPERABLE two (2) independent RHR' shutdown cooling subsystems means that.each subsystem considered OPERABLE must be associated with a different heat exhanger loop, i.e., the "A" RHR heat exchanger with the "A" RHR pump or the "C" RHR pump, And the "B" RHR heat exchanger with the "B" RHR pump or the "D" RHR pump are two (2) independent RHR shutdown cooling subsystems. Only one (1)'.of the the two (2) RHR pumps associated with each RHR heat exchanger loop is LIMERICK - UNIT 1 B 3/4 4-6 Amendment No. 497 -97 7 119 FEB 31997 m .
