SAFETY EVALUATION RE: Turkey Point Unit Nos. 3 8 4 Docket Nos. 50-250 and 50-251 Pro osed. Tech S ec Amendment Introduction This evaluation supports a proposal to revise Specification 4.2. 1,
".Reactor Coolant System In-Service Inspection", Table 4.2-1,. Item No. 7. 1 Reactor Coolant Pump Flywheel Inservice Inspection, to conform to the the requirements of Regulatory Guide No. 1. 1'4, Revision 1, August 1975, and Section XI of the ASME Boiler and .Pressure Vessel. Code..
I I. Di scussi on The proposed revision to Technical Specification 4.2.1, Table 4.2.1, Item Ho. 7.1's necessary to conform Speci'fication 4.2.1 to the requirements of Regulation Guide 'No. 1.14 and Section XI of the ASME Boiler and Pressure
'Vessel Code. This proposed revision does not alter. the design philosophy for In-Servi'ce Inspection discussed in FSAR Secti'on 4.4.1 and as such will continue,to.ensure that as a mimimum, the assumptions used in the safety analyses are met and the operabili.ty of the reactor coolant pump flywheels are maintained.
I I I I. Conc 1 usi on, Me have concluded, based on the considerations discussed, above, that:
'(1) the. amendment does .not involve a significant increase in the probability or consequences of accidents, previously considered and: does not involve a significant decrease in a safety, margin, (2), there is reasonable'ssurance that the health. and safety. of the publ.i.c will not be endangered by operation in the proposed manner, and (3) such activities will be conducted'n compliance with the Commission' .regulations and the issuance of this amendment, will. not be inimical to the common defense and security or to the
.health and: safety:of the pub.lic.
