ST. LUCIE - UNIT 1 3/4 7-9 Amendment No. 80,

418 APPLICABILITY BASES Surveillance Requirements do not have to be performed on inoperable equipment 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 OPERABLE status.

4.0.4 This specification establishes the requirement that all applicable surveillances must be met before entry into an OPERATIONAL MODE or other condition of operation specified in the Applicability s.atement. The purpose of this specification is to ensure that system and component OPEPABILITY requirements or parameter limits are met before entry into a MOOE or condition

'for which these systems and components ensure safe operation of the facility.

This provision applies to changes in OPERATIONAL MOOES or other specified conditions associated with plant shutdown as well as startuo.

Under the provisions of this specification, the applicable Surveillance Requirements must be performed within the specified surveillance interval to ensure that the Limiting Conditions for Operation are met during initial plant startup or following a plant outage. d Nhen a shutdown is required to comply with ACTION requirements, the provisions of Specification 4.0.4 do not apply because this would la placing the facility in a lower MOOE of operation.

4.0.5 This specification ensures that inservice inspection of ASME Class 1, 2 and 3 components aA d-d 3-pumps-and-vaWes we'll be performed in accordance with a periodically updated d~

version of Section XI of the ASh(E Boiler and Pressure Vessel Code and Addenda.

as required by 10 CFR 50.55a. Relief from any of the above requirements has Code been provided in writing by the Commission and is not a part of these Technical

,Specifications.

431 REACTOR COOLANT SYSTEM BASES 3/4.4.2 and 3/4.4.3 SAFETY VALVES (Conti'nued)

During operation, all pressurizer, code safety valves 'must be OPERABLE to prevent the RCS from being pressurized above its safety limit of 2750 psia. The combined relief capacity of these valves is sufficient to limit the Reactor Coolant System pressure to within its Safety Limit of 2750 psia following a complete loss of turbine generator load while operating at RATED THERMAL POMER and assuming no reactor trip until the first Reactor Protective System trip setpoint (Pressurizer Pressure-High) is reached (i.e., no credit is .aken for a direct reactor trip on the loss of turbine) and also assuming no operation of the pressurizer power operated relief valve or steam dump valves.

Demonstration

~ME-8 3/4.4.4 H

PRESSURIZER

~6 of the safety valves'ift settings will occur only during h

A steam bubble in the pressurizer ensures that the RCS is not a hydrauli-cally solid system and is capable of accommodating pressure surges during opera-tion. The steam bubble also protects the pressurizer code safety valves and power operated relief valve against water relief. The power operated relief valve and steam bubble function to relieve RCS pressure during all design transients. Operation of the power operated relief valve in conjunction with a reactor trip on a Pressurizer-Pressure-High signal minimizes the undesirable opening of the spring-loaded pressurizer code safety valves. The required pr essurizer heater capacity is capable of maintaining natural circulation sub-cooling. Operability of the heaters, which are powered by a diesel generator bus, ensures ability to maintain pressure control even with loss of offsite power.

3 4.4.5 STEAM GENERATORS One OPERABLE steam generator provides sufficient heat removal capability to remove decay heat after a reactor shutdown. The requirement for two steam generators capable of removing decay heat, combined with the requirements of Specifications 3.7.1.1, 3.7.1.2 and 3.7.1.3 ensures adequate decay heat removal capabilities for RCS temperatures greater than 325 F if one steam generator becomes inoperable due to single failure considerations. Below 325 F, decay heat is removed by the shutdown cooling system.

The Surveillance Requir ements for inspection of the steam generator tubes ensure that the structural integr ity of this portion of the RCS will be main-tained. The program for inservice inspection of steam generator tubes is based on a modification of Regulatory Guide 1.83. Revision l. Inservice inspec-tion of steam generator tubing is essential in order to maintain surveillance of the conditions of the tubes in the event that there is evidence of mechanical demage or progressive degradation due to design, manufacturing errors, or in-service conditions that lead to corrosion. Inservice inspection of steam generator tubing also provides a means of characterizing the nature and cause of any tube degradation so that corrective measures can be taken.

BASES 4.0.4 This specification establishes the requirement that all applicable condition surveillances must be met before entry into an OPERATIONAL MODE or otherthis of operation specified in the Applicability statement. The purposerequirements of specification is to ensure that system and component OPERABILITY or parameter limits are met before entry into a MODE or condition for which these systems and components ensure safe operation of the facility. This provision applies to changes in OPERATIONAL MOOES 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 that the Limiting Conditions for Operation are met during initial plant startuo or 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 facility in a lower MODE of operation.

4.0.5 This specification ensu'res that inservice inspectio of ASME Code II Class 1, 2 and 3 components an imps-an~+es will 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.

During operation, all pressurizer code safety valves must be OPERABLE to prevent the RCS from being pressurized above its safety limit of 2750 psia.

The combined relief capacity of these valves is sufficient to limit the system pressure to within its Safety. Limit of 2750 psia following a complete loss of turbine generator load while operating at RATED THERMAL POWER and assuming no reactor trip until the first Reactor Protective System trip .setpoint (Pres-surizer Pressure-High) is reached (i.e., no credit is taken for a direct reactor trip on the loss of turbine) and also assuming no operation of the pressurizer power-operated relief valve or steam dump valves.

Demonstration of the safety valves'ift settings will occur only during shutdown and will be performed in accordance with the provisions of See&ca-4I ofhe-ASM 3/4.4.3 PRESSURIZER HAe aur yacc'arsi~

An OPERABLE pressurizer provides pressure control for the Reactor Coolant System during operations with both forced reactor coolant flow and with natural circulation flow. The minimum water level in the pressurizer assures the pressurizer heaters, which are required to achieve and maintain pressure control, remain covered with water to prevent failure, which could occur if the heaters were energized uncovered. The maximum water level in the pres-surizer ensures that this parameter is maintained within the envelope of operation assumed in .he safety analysis. The maximum water level'lso ensures that the RCS is not a hydraulically solid system and that a steam bubble will be provided to accommodate pressure surges during operation. The steam bubble also protects the pressurizer code safety valves against water relief. The requirement to verify that on an Engineered Safety Features Actuation test signal concurrent with a loss of offsite power the pressurizer heaters are automatically shed from the emergency power sources is to ensure that the non-Class lE heaters do not reduce the reliability of or, overload the emergency power source. The requirement that a minimum number of pressurizer heaters be OPERABLE enhances the capability to control Reactor Coolant System pressure and establish and maintain natural circulation.
