STARTUP TEST PROCEDURE 9 WATER LEVEL MEASUREMENT

1. PURPOSE A. The purpose of this test is as follows:

1. To check the calibration of the various narrow range and wide range indicators.

2. To measure the reference leg temperature and recalibrate the narrow and wide range instruments if the measured temperature is different than the value assumed during the initial calibration.

3. To collect plant data which can be used to investigate the effects of core flow velocity, carry-undar, and subcooling on indicated wide range level.

2. CRITERIA Level 2 A. The narrow range level indicator readings on the instruments used for feedwater level control (lC34-R606A-C) should agree within + 1.5 inches of their average reading.

B. The narrow range level indicator readings on the instruments not used for feedwater level control (lB21-N024A-D, 1B21-N038A-B, 1B21-N100A-B, and 1B21-N101A-B) should agree within + 3.0 inches of their average reading.

C. The wide range level system indicators (lB21-N026A-D, 1B21-NO31A-D, 1B21-NO36A-D, 1B21-N037A-D, 1B21-R604, 1C61-R010, 1B21-R623A-B should agree within + 6 inches of the average reading.

3. RESULTS Test Condition 3.

All narrow and wide range level instruments satisfied their respective level 2 criteria (see Table 1) .
