Recently, Georgia Power Ccepany (GPC) determined that the upcming refueling outage for Plant Hatch Unit 1 will last approximately ten weeks, beginning around October 1, 1984. The details of this decision are outlined in two previous GPC subnittals to the NRC dated May 31 and July 6, 1984 (NED-81-280 and NED-84-369, respectively).

GPC is in the process of installing new Cmsip-Delphi drywell rfydrogen (H ) and Oxygen (0 ) Analyzers on Hatch-2 as part of the effort to meet 2

2 the requirements of 10 CFR 50.49.

It is currently estimated that this work will have required 25 weeks of outage time (and 16,300 craft man-hours) when

't is empleted prior to unit startup.

Since installation of this new sluipnent rquires emplete removal of the existing analyzers, this work must be performed while the unit is shutdown and cmpleted during the outage in which it was begun.

GPC had originally intended to install new H2 and 02 analyzers on Unit 1 during the upcming outage, in order to meet the deadline requirenents of 10 CER 50.49(g).

However, since this installation would not be feasible during a ten week outage, the latest planning calls for replacanent of the existing Unit 1 analyzers during the refueling outage scheduled for the Fall of

1985, h refore, GPC requests that a

qualification deadline extension to Novenber 30, 1985 be granted, under the provisions of 10 CFR 50.49 (g),

for the existing Hatch-l H2 and O2 analyzers.

i Director of Nuclear Reactor Regulation Attention: Mr. John F. Stolz, Chief Operating Reactors Branch No. 4 July 17, 1984 Page Two GK has been proceeding with the installation of the Hatch-2 analyzers, even though the qualification testing for this new equipent is far fra cmplete, with the expectation that the analyzers will be found suitable for use at Plant Hatch.

Casip, Inc.- recently informed GPC that the qualification testing program schedule had been delayed due to procurement problens.

%e current schedule for qualification testing and analysis for the H2 and 02 analyzers for both Hatch units (see analyzer models will be used on both units) is outlined in Enclosure 1.

GPC expects to be able to declare these analyzers as fully qualified for use at Plant Hatch by the end of 1984, using the results of the Capsip 30-day interim test report.

%e final 180-day IDCA test will be performed only as an additional j

confirmation of qualification..

i Hatch-2 is currently scheduled to restart in late July 1984.

Since the H2 and 02 analyzers will probably not be qualified until the end of 1984, GPC requests that a qualification deadline extension to March 31, 1985 be granted, under the provisions of 10 CFR 50.49(g), for the new Hatch-2 H2 and O2 analyzers.

%e additional time requested beyond the end of 1984 would allow for any unforeseen delays which could occur during the q'ualification testing process.

GPC has made a diligent effort to meet the requirenents of 10 CFR-50.49 within the time prescribed in paragraph (g) of that rule.

Plant Hatch has

' enbarked on an extensive progran of backfitting and equipent replacanent to e

ensure that all applicable equipnent meets the intent of 10 CFR 50.49.

In many ' cases GE has performed costly and time-consuning replacements of sluipnent rather than relying on marginally-acceptable engineering analyses to prove that necessary equipnent would perform its intended function during or after an accident.

GPC believes that the superiority of the new Cmpsip-Delphi H2 and O2 analyzers over the equipnent which tney replace in terms of expected instrunent ' reliability, as well as qualification assurance, outweighs the problems and delays experienced during installation and testing.

%e long-term gain in overall plant safety and performance expected fra these new devices justifies the requested short-term ' extensions of the qualification deadlines; also GPC has subnitted

" Justifications for Continued Operation" for the plant using' the instrunents which these new analyzers will replace.
