2.1.1 Emergency Power Supply Requirement (partially) 2.1.3.a Direct Indication of Valve Position 2.1.3.b Instrumentation for Inadequate Core Cooling 2.2.1.b Shift Technical Advisor

! The proposed change also deletes the 11% acceptance value associated with the relief valve setpoint (specifications 3.4.2 and 3.4.3.1), due to inconsistency with ASME Code, and impropriety in having accuracy range in a Limiting Condition for Operation.

Reasons for Proposed Change These changes are in respon:.e to Mr. Darrell Eisenhut's (Director, USNRC, Division of Licensing) letter of July 2,1980. Items included in Mr. Eisenhut's letter which were not included in this Technical Speciff-cation Change Request are discussed in the letter to which this is attached.

Safety Analysis Justifying the Proposed Change The changes proposed include installed modifications into the Technical Specifications. These modifications were required as part of the imple-mentation of NUREG-0578, Category A items. The Staff reviewed these modifications as part of their review of all Lessons Learned changes and have issued a Safety Evaluation (dated May 5,1980)-on the system, as modified.

. . .a 3/4.4 REACTOR COOLANT SYSTEM BASES 3/4.4.1 REACTOR COOLANT LOOPS The plant is designed to operate with both reactor coolan.t loops in op-eration, and maintain DNBR above 1.30 during all normal operations and anticipated transients. With one reactor coolant pump not in operation in one loop, THERMAL POWER is restricted by the Nuclear Overpower Based on RCS Flow and AXIAL POWER IMBALANCE, ensuring that the DNBR will be maintained above 1.30 at the maximum possible THERMAL POWER for the num-ber of reactor coolant pumps in operation or the local quality at the point of minimum DNBR equal to 22%, whichever is more restrictive.

A single reactor coolant loop provides sufficient heat removal capabili-ty for removing core decay heat while in H0T STANDBY; however, single failure considerations require placing a DHR loop into operation in the shutdown cooling mode if component repairs and/or corrective actions cannot be made within the allowable out-of-service time.

3/4.4.2 RELIEF VALVES - SHUTDOWN The pressurizer code safety valves. operate to prevent the RCS from being pressurized above its Safety Limit of 2750 psig. Each safety valve is designed to relieve 317,973 lbs per hour of saturated steam at the valve's setpoint.

The relief capacity of a single safety valve is adequate to relieve any overpressure condition which could occur during shutdown. In the event that no safety valves are OPERABLE, an operating DHR loop, connected to the RCS, provides overpressure relief capability and will prevent RCS overpressurization.

During operation, all pressurizer code safety valves must be OPERABLE to prevent the RCS from being pressurized above its safety limit of 2750 psig. The combined relief capacity of all of these valves is greater than the maximum surge rate resulting from any transient.

Demonstration of the safety valves' lift settings will occur only during shutdown and will be performed in accordance with the provisions of Sec-tion XI of the ASME Boiler and Pressure Code.

3/4.4.3 RELIEF VALVES - OPERATING

.The power operated relief valve (PORV) operates to relieve RCS pressure below the setting of the pressurizer code safety valves. This relief valve has a remotely operated block valve to provide a positive shutoff CRYSTAL RIVER - UNIT 3 B 3/4 4-1

REACTOR C00LANT SYSTEM BASES capability should the PORV become inoperable. The electrical power for both the relief valve and the block valve is capable of being supplied from an emergency power source to ensure the ability . to seal this ~

possible RCS leakage path.

3/4.4.4 PRESSURIZER A steam bubble in the pressurizer ensures that the RCS is not a hydrau-lically solid system and is capable of accommodating pressure surges during operation. The steam bubble also protects the pressurizer code safety valves and power operated relief valves against water relief.

The low level limit is based on providing enough water volume to prevent a pressurizer low level or a reactor coolant system low pressure condi-tion that would actuate the Reactor Protection System or the Engineered Safety Feature Actuation System as a result of a reactor scram. The high level limit is based on maximum reactor coolant inventory assumed in the safety analysis.

The power operated relief valves and steam bubble function to relieve RCS pressure during all design transients. Operation of the power oper-ated relief valves minimizes the undesirable opening of the spring-loaded pressurizer code safety valves.

3/4.4.5 STEAM GENERATORS The Surveillance Requirements for inspection of the steam generator tubes ensure that the structural integrity of this portion of the RCS will be maintained. The program for inservice inspection of steam gen-erator tubes is based on a modification of Regulatory Guide 1.83, Re-vision 1. Inservice inspection of steam generator tubing is essential in order to maintain surveillance of the conditions of the tubes in the event that there i; evidence of mechanical damage or progressive degra-dation due to design, manufacturing errors, or inservice conditions that lead to corrosion. Inservice inspection of steam generator tubing also provides a means of characterizing the nature and cause of any tube de-gradation so that corrective measures can be taken.

CRYSTAL RIVER - UNIT 3 B 3/4 4-2

I REACTOR C0OLANT SYSTEM BASES The plant is expected to be operated in a manner such that the secondary coolant will be maintained within those chemistry limits found to result in negligible corrosion of the steam generator tubes. If. the secondary coolant chemistry is not maintained within these chemistry limits, localized corrosion may likely result in stress corrosion cracking. The extent of cracking during plant operation would be limited by the limi-tation of steam generator tube leakage between the primary coolant system and the secondary coolant system (primary-to-secondary leak-age = 1 GPM). Cracks having a primary-to-secondary leakage less than this limit during operation will have an adequate margin of safety to withstand the loads imposed during normal operation and by postulated accidents. Operating plants have demonstrated that primary-to-secondary leakage of 1 GPM can be detected by monitoring the secondary coolant.

Leakage in excess of this limit will require plant shutdown and an un-scheduled inspection, during which the leaking tubes will be located and pl ugged.

Wastage-type defects are unlikely with proper chemistry treatment of the secondary coolant. However, even if a defect should develop in service, it will be found during scheduled inservice steam generator tube exami-nations. Plugging will be required for all tubes with imperfections ex-ceeding the plugging limit of 40% of the tube nominal wall thickness.

Steam generator tube inspections of operating plants have demonstrated the capability to reliably detect degradation that has penetrated 20% of the original tube wall thickness.

Whenever the results of any steam generator tubing inservice inspec-tion fall into Category C-3, these results will be promptly reported to the Commission pursuant to Specification 6.9.1 prior to resumption of plant operation. Such cases will be considered by the Commission on a case-by-case basis and may result in a requirement for analysis, labora-tory examinations, tests, additional eddy-current inspection, and revi-sion of the Technical Specifications, if necessary.

The steam generator water level limits are consistent with the initial conditions assumptions in the FSAR.
