References (1) and (2) transmitted for our review and evaluation a response frota Philadelphia Electric Co. (reference 3) regarding an inspection report unrcsolved ites (reference 4) identified during post-tensiontag the fuel pool cfrders at Limerick Unit 1 Station. The ites identified the need f;r qualification tests addressing slippage of the wedge anchors during pr2 stressing and the use of a monostrand jack to recover the prestress 1 css due to slippage.

We have reviewed the sutaittal by PEco which includes an engineering evaluation perfsrmed by Bechtel and results of VSL Corporation's qualiffcation tests of the post-tensioning systen caterials and field procedures. The results of our review are:

1 1.

The qualification tests conducted by YSL verify that the capacity of j

the anchorage systen is capable of meeting design requirements.

2.

Variations in prescating the wedge anchors and the use of a monostrand ram should not affect the applicability of the qualification tests.

3.

The evaluations performed by PECo Bechtel and VSL adequately address the identified unresolved item.
