~Mr. Harold.R. Denton, Director Offi of Nuclear Beactor Regulation >

U.S. ' Nuclear Regulatory Comission Whshington, D.C. 20555 .

Dear Mr. Denton:

River ~ Bend Station - Unit 1 Docket No."50-458

%e final rule ~ for cabustible ; gas control was published in.the Federal Register on January 25,:1985. % e rule requires that a hy l vgeni control . ' system justified by a suitable progre of testing and analysis be provided in Mark III contaiment plants such as River Bend Station.

%e rulei also requires that applicants develop and sutmit a pivr ead schedule for meeting the requirements of the final _ rule (10 CPR 50.44, paragraphs (c) (3) (iv) , (v)', and (vi)) .s GSU is a menber of the: Hy &&a Control Owners' Group and is actively supporting ccspletion' of the progra elements described in the HOOG Hy& uysn Control Progr e Plan:(sutnitted to the NRC on D + 2+r 14, 1985) . : GSU's pt ,-*3 schedule for ccsplying with the hydrogen rule as it applies to the River Bend Station,is attached.- h is schedule shows p --:*1 coupletion dates for the generic: tasks as well as River Bend Statie - specific activities. As shown, a hy& vveu control system for

-the x Bend Station has been designed, installed, and tested.

%e final rule also requires'that analysis which supports the design of. the hy&vycai control system be subnitted to the Nuclear Regulatory Ocamission. As delineated in 10' CPR 50.44 paragrat ia (c) (3) (vii) (B) ,

. final analyses are not n-===ry provided that preliminary analysis

' ' which muwvii interim operation at. full power are supplied. As shown in the attached schedule, RBS's contaiment ultimate pressure capacity-analysis and.contalment response to hydrogen burns (CIASIX-3) analysis are ocuplete and~ have been supplied previously. A list of equipnent required to survive a hy&us n; burn and a . preliminary equipnent survivability analysis of postulated hy& vven c mbustion within the RBS.

contaiment will be subnitted by Jtily 1,1985. % ese analyses support a decision to allow interim operation of River Bend Station at full power.
