STARTUP TEST PROCEDURE 33 DRYWELL PIPING VIBRATION

1. _P_URPOSE A. The purpose of this test is to verify that the main steam, reactor recirculation, and feedwater piping have acceptable vibration.
2. CRIILdIA Level 1.

A. The measured amplitude for vibration of the recirculation system during recirculation pump trips and subsequent coast down shall not exceed the allowable values.

B. The measured amplitude for vibration of the main steam lines during relief valve operation shall not exceed allowable values.

C. The measured amplitude for steady state vibration of the recircula-tion and main steam systems shall not exceed allowable values.

D. The measured amplitude for vibration of the main steam lines due to turbine stop valve trip and relief valve operation shall not exceed allowable' values.

Level 2.

A. The measured amplitude of vibration of the main steam system following relief valve operation and turbine stop valve trip should not exceed the expected values.

B. The measured amplitude of vibration of the main steam and recircula-tion systems during steady state operation should not exceed the expected values.

C. The measured vibrational stresses induced in the feedwater system following trip of one and both turbine driven feed pumps and during steady state operations should not exceed the expected stresses.

3. RESULTS Test Condition 3.

Steady state vibration measurements were performed, and the results were satisfactory. Further testing will be performed in Test Condition 3 in conjunction with relief valve testing, main turbine trip, and recirc pump trip and start.
