2.7 EFFECT OF STEAM GENERATOR SECONDARY SIDE ISOLATON i DN NATURAL CIRCULATION (TEST 4) i l

Objective - To determine the effects of steam generator secondary side isolation on natural circulation.

Method - Establish natural circulation conditions as in Test 2a but at 1% power. Isolate the feedwater and steam line for one steam generator and establish equilibrium. Return the steam generators to service in reverse order.

2.8 ESTABLISHMENT OF NATURAL CIRCULATION FROM STAGNANT CONDITIONS Westinghouse does not believe that it is advisable to perform this test as noted in a letter from T. M. Anderson, Westinghouse, to H. Denton, NRC, NS-TMA-2242, April 29, 1980.

2.9 FORCED CIRCULATION COOLDOWN (TEST 5)

This test establishes the initial conditions necessary for Test 4, .

Effect of Steam Generator Secondary Side Isolation On Natural Circulation. Any evaluations, technical specification exceptions or analysis necessary to bound the consequences of this test are the same as Tes t 4. (Note: This test (5) is performed as part of test 4 above)

• 2.10 BORON MIIING AND COOLDOWN Westinghouse does not believe that it is advisable to perform this test utilizing core heat as noted in NS-TMA-2242, T. M. Anderson, Westinghouse, to H. Denton, NRC.
