Attention: Mr..B. J. Youngblood, Project Director PWR Project. Directorate No. 4 RE: Catawba Nuclear Station, Unit 2 Docket No. 50-414

Dear Sir:

Mr. B. J. Youngblood's letter of February 3, 1986 transmitted a preliminary draft of the proposed low power license for Catawba Unit 2. We have reviewed this document to ensure that it accurately reflects commitments either made by Duke Power Company in the Catawba FSAR or other documents or required of Duke in the SER or other documents.

Our comments on the proposed low power license are attached.

Very truly yours,

/fd Hal B. Tucker ROS:slb Attachment cc: Dr. J. Nelson Grace, Regional Administrator U. S. Nuclear Regulatory Commission Region II 101 Marietta Street, NW, Suite 2900 Atlanta, Georgia 30323 NRC Resident Inspector l Catawba Nuclear Station 1

- .N Duke Power Company Catawba Nuclear Station Unit 2 Comments on the Proposed Low Power License (1) Comment: 2.B.(2) should refer to 10 CFR Part 50 not Part 70.

Reason: Consistency with 2.B. (1) .

(2) Comment: License Condition 2.C.(8) -delete reference to February 20, 1984.

Reason: February 20, 1984 letter addressed the schedule for correction of HED's on Catawba Unit 1. The letter did not address Catawba Unit 2.

(3) Comment: License Condition - 2.C. (9)- (a) and .(b) - These license conditions are apparently based on Staff positions discussed in SSER-5 which has not been issued. We are therefore unable to comment on the technical merit of these license conditions and

~

would preserve our option to further discuss these issues with the Staff after SSER-5 is issued.

(4) Comment: License Condition 2.C. (13) - As discussed in my letter of December 3, 1985, previously committed activities related to Generic Letter 83-28 are essentially complete except for Item 4.2.2. This item, while currently on-schedule, depends on a submittal by the Westinghouse Owners Group (WOG) as discussed in L. D. Butterfield's letter (OG-167) to R. J. Wright, NRC, dated December 9, 1985. If there is any further delay in the WOG submittal, an amendment to the Catawba Units 1 and 2 licenses would be necessary.

(5) Comment: 2.F should refer to ... Items C. (1) , C. (3) through C.(13) ... rather than C.(15).

Reason: There are only 13 License Conditions currently identified.

(6) Comment: Attachment 2 Since the preliminary draft of the low power license was transmitted on February 3, 1986, it is our understanding that a number of changes have been made to Attachment 2. We have no comments on these changes. Our only comment is noted below.

?or * %

Item 4:. Change last sentence to read:

"No cylinder heads that contain a through-wall. weld repair where the repair was performed from one side only and the root was not machined out shall be used on the engines" -

Reason:

To highlight how full penetration welds are made by TDI. The intent is to eliminate partial penetration welds on cylinder heads. Full penetration-welds, which are acceptable,. ara made by welding from one side and then grinding the root out.
