Dear Mr. Lundvall:

The code relief, granted in accordance with 10 CFR Part 50, Section 50.55a(g)(6)(1),

relates to the requirement for pressure testin with the High Pressure Safety Injection (HPSI)g , Auxiliary of Class HPSI,2 and piping Lowassociated Pres-sure Safety Injection (LPSI) Loop Isolation MOVs to the Reactor Coolant System.

You have proposed acceptable, alternate testing as described in the enclosed Safety Evaluation.

We have detemined that the testing for which relief has been requested and approved is impractical and pursuant to 10 CFR 50.55a(g)(6)(1), that the granting of this relief is authorized by law and will not endanger life or property or the comon defense and security and is othersise in the public interest. In making this determination, we have given due consideration to the burden that could result if these requirements were imposed on your facility.
