Subject:
Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 IST (Inservice Test) Program; Proposed Revision 1E The purpose of this submittal is to request NRC review and approval of Proposed Revision IE to the Unit No. 1 IST Program.
Pump Relief Request No.
3 was previously approved granting relief from monitoring flow during quarterly testing of the boric acid transfer 1
pumps.
The alternative test is a refueling frequency full-flow test which measures pump differential pressure and calculates flow.
The attached proposed relief request revises the full-flow test-performed a
during refueling outages while leaving the quarterly test unchanged.
The existing full-flow test measures flow by measuring the change in tank level over time as the process fluid is pumped from one boric acid tank to the other.
The new full-flow test would install a portable ultrasonic flow meter on the recirculation flow path.
This new test would be much easier to perform and have less impact on the refueling schedule.
In
- addition, the use of the calibrated ultrasonic flow meter would increase the repeatability of the test by eliminating some test performance
- issues, such as difficulty in i
throttling and in measuring inlet pressure.
It was determined that a
new relief request was necessary for this test change because part of the basin in the NRC SER (Safety l
Evaluation Report) for approving the previous relief request was the difficulty in performing and scheduling the full-flow test.
It is requested that the NRC complete the review of this proposed relief request in time to support implementation of the revised full-flow testing during the tenth refueling outage currently scheduled to begin October 7, 1994.
