SPECIAL TEST 2-50 On December 5, 1985, Special Test 2-50 was completed. This was the Unit 2 Cycle 8 Startup Tcst Program, which was conducted to gather information on unit performance following the startup from Cycle 7 refueling.
Safety Evaluation 1.
The probability of an occurrence or the consequence of an accident, or malfunction of equipment important to safety as previously evaluated in the FSAR is not increased by any of the startup tests.
The unit will be operating at normal startup and steady state operating conditions.
No unusual or unanalyzed valve or equipment configurations are called for by any of the test procedures. The startup program is made up entirely of existing station procedures.
All data vill be taken externally, that is, data acquisition will not interfere in any way with normal system operation.
No tests will be performed which will affect the capability for safe shutdown of the plant, or jeopardize the safety of the public.
2.
The possibility for an accident or malfunction of a different type than any previously evaluated in the FSAR is not created. The normal function and intent of all systems involved in the testing will not be altered. No new type of equipment is to be installed which has not been analyzed previously. No now valve line-ups or special operating procedures will be used in conducting any of the startup tests.
3.
The testing program itself will not reduce the margin of safety as defined in the basis for any Technical Specification.
In fact, the purpose of the Startup Test Program is to satisfactorily demonstrate that Technical Specifications can be met and that the plant may continue to operate safely.
