Reference:

Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 NRC Bulletin 88-11 Gentlemen:

In accordance with Item 1.a of Bulletin 88-11, " Pressurizer Surge Line. Thermal-Stratification", we performed a visual inspection (ASME,Section XI, VT-3) of the Beaver Valley Unit 1 (BV-1) pressurizer surge line during the seventh refueling

. outage.

No discernible distress or damage was identified for the pressurizer surge line piping, supports, pipe whip restraints, and anchor bolts.

However, during the inspection of this line, the rupture restraint gaps were found to be open greater than the original

-design ~ analysis and-the rupture restraints baseplate to embedments were welded together and the shear bars / lugs were not' installed.

These deficiencies were reported in Licensee Event Report (LER) 89-011-00.

Both of the deficiencies were corrected during the seventh refueling outage.

We are continuing our efforts to complete the BV-1 plant

specific analyses for Item 1.d of the Bulletin by January, 1991.

If you have any questions concerning this response, please contact my office.

Very truly yours,
