HATCH NUCLEAR PLANT UNITS 1, 2 P0TENTIAL 10 CFR 50.49 DEADLINE IMPACT DRYWELL HYDROGEN AND OXYGEN ANALYZERS Gentlemen:

Georgia Power Company (GPC) 'hereby notifies the NRC, pursuant to 10 CFR 50.49(h), of significant problems outlined below which could require a request for extension of the 10 CFR 50.49(g) equipment qualification deadline for Plant Hatch's Primary Containment Hydrogen (H )2 and Oxygen (02 ) gas analyzers. These analyzers are currently installed on Plant Hatch Unit 2 and are awaiting installation on Unit 1. On June 4, 1985, GPC was informed by the analyzer vendor, Comsip Inc. (through our Architect-Engineer, Bechtel Power Corporation) that a -delay had occurred in the Loss Of Coolant Accident (LOCA) qualification testing for the heat tracing on the tubing which feeds these analyzers.

By ~ our previous correspondence NED-84-383, NED-84-514, NED-85-061, and NED-85-195 dated July 17, 1984, October 4, 1984, March 1, 1985, and March 27, 1985, respectively, GPC requested or amended requests for extension of the qualification deadline for these gas analyzers. As was detailed in the above referenced submittals, the primary bases for these extension requests.

were delays which have continually plagued the qualification testing effort

~

being conducted by Comsip, Inc. These requests were granted by NRC letters dated August 6,-1984, November 30, 1984, and March 27, 1985.

The schedular delays being sxperienced during qualification of the heat tracing are not necessarily unique to Plant Hatch. The LOCA qualification testing being performed is for an environmental envelope which is expected to be similar to that predicted for other. BWR licensees. Thus, we expect that other customers of Comsip, Inc. may be similarly affected by schedular delays. Delays resulting in deadline impacts which are due to qualification testing for equipment covered by 10 CFR 50.49 in general are certainly not unique to Plant Hatch.

,e GeorgiaPowerI Director of Nuclear Reactor Regulation Attention: Mr. John F. Stolz, Chief Operating Reactors Branch No. 4 August 16, 1985 Page Two This latest delay was due to an anomaly which occurred during the LOCA phase of the test program. Comsip has resolved the anomaly and is planning to reinitiate testing in the near future. However, this incident has forced a revision of the testing schedule which was submitted to the NRC as an Enclosure to NED-85-061. The most recent schedule for completion of the testing and the associated reports as verbally transmitted by the vendor is enclosed with this letter.

If Comsip is able to submit the thirty day interim test report within the enclosed schedule, then GPC should be able to declare the Plant Hatch H

2 and 02 analyzers to be environmentally qualified by the current deadline of November-30, 1985. However, this entire effort has experienced repeated delays due to unforeseen difficulties and the industry-wide demand on the limited number of facilities available to perform testing which meets the requirements of 10 CFR 50.49.

GPC is following the progress of the analyzer testing closely and intends November to30,make every practical effort to resolve this issue prior to 1985. However, should it become apparent that the qualification deadline can not be met for these equipment items, then GPC will promptly submit an extension request.

Should you have any questions regarding this issue, please contact this office.

Sincerely yours, f)0ubM L.T. Gucwa CBS Enclosure xc: J. T. Beckham, Jr.
