Beaver Valley Power Station, Unit.No. 2 Docket No. 50-412, License No. NPF-73 Correction to Unit No. 2 Ten Year ISI Program; Relief Request BV2-C6.10-1 Gentlemen:
This submittal forwards a correction to the Beaver Valley Unit No. 2 First Ten Year Inservice Inspection Program (Rev. 1).
Specifically, relief request BV2-C6.10-1, Rev. 1 was submitted on January: 5, 1990, in response to your request for additional information dated November 20, 1989.
Upon additional in-house review it was determined that the referenced relief request incorrectly included reference:to volumetric examination in the Basis for' Relief and Alternative Examination.
These two parts of the relief request should have used the term surface examination.
