Washington Public Power Supply System P.O. Box 968 3000George Washington Way Richland, Washington 99352 t509) 372-5000 Docket No. 50-397 Responds to: N/A July 8, 1983 Response required by: N/A G02-83-611 Director of Nuclear Reactor Regulation Attention: Mr. A. Schwencer, Chief Licensing Branch No. 2 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D. C. 20555

Subject:

NUCLEAR PROJECT NO. 2 PROPOSED SNUBBER TECHNICAL SPECIFICATION The proposed Snubber Technical Specification for WNP-2 is enclosed for your review as a follow-on to the telephone, conversations between Horace Shaw and Larry Prill of the Supply System on March 14, and June 24, 1983.

A summary of the differences in this proposed specification in com-parison with the standard technical specification is as follows:

1. The first visual examination scheduled to occur at 4 to 10 months following power operation will be done as part of the WNP-2 Pre-seryice Component Support Inspection Program. This post-shakedown inspection is to be performed following plant operation at power and after at least three full thermal cycles of plant systems which meets the intent of the standard technical specification.

A copy of the Preservice Component Support Inspection Program is included as Attachment A.

2. Paragraph 4.7.4.d, entitled "Functional Testing," has been ex-panded to include three sample optional plans, all of which pro-vide 95% probability that 90 to 100% of the safety-related plant snubbers are operational. The additional sample plan options are identical to those currently in the staff approved McGuire Unit Technical Specifications and, thus, should provide no 1

difficulty in receiving staff approval.

Mr. A. Schwencer Page Two July 8, 1983 PROl'OSED SNUBBER TECHNICAL SPECIFICATION

3. Paragraph 4.7.4.e has the added specification that functional testing of snubbers be performed at greater than or equal to 10% snubber rated load. Additionally, the clarification is made in this paragraph that an increase in snubber drag force counts as a failed snubber only when the drag force exceeds the maximum specified drag force for the snubber.

It is the Supply System's position that these changes will not lessen the assurance of structural integrity and functionality of NNP-2 safety-related systems but will reduce the impact of this technical specification on WNP-2.

Fuel load is scheduled for September 1983 and your expeditious review of the enclosed is appreciated. Please call Messrs. P. Powell at (509) 377-2501 extension 2909 L. Pri ll at (509) 377-2522 extension 4523 with your questions or comments.
