The enclosed information provides a description of the actions taken to date for operating reactors with regard to a potential unrevie..ed safety question on interaction between non-saftty grade systems and safety grade systems.
Although comparable actions ~have not yet been taken for plants under licensing review we are providing this information to all Boards. This matter will be addressed for these plants and you will be provided with the ongoing staff assessment as it develops.

SUBJECT:
POTENTI AL UNREVIEWED S AFETY QUESTICN ON IN~ERACTION EETWEEN NON-SAFETY GRADE SYSTEMS AND SAFETY GRADE SYSTEMS You were infomed by TE Information Notice 79-22, issued Septemaer 14, 1979, that certain r.on-safety grade equipment, if subjemted to an acierse er.vircr-ment, could inpact the safety analyses ar.d the adequacy of the protective functions perfomea by safety grade equipment.
Enclosed is a copy of IE Infomation Notice 79-22, and reprinted copies of an August 30, 1979 Westinghouse letter and a September 10, 1979 Public Service Electric and Gas Company letter which address this matter.
The NRC is concerned that a similar potential may exist at other cperating light water reactor f acilities, including ycurs, for an unreviewed safety natter related to the effects of the environment on control systens result,ng from high energy lir.e breaks inside or outside containment and the results of these effects on the required safety systens.
In accordance with 10 CFR 50.54(f) you are rectested to provide within twenty (20) cays of the date of this letter, written statements, signed under oath or affirmation, which will enable the staff to determine, in light of the concerns discussed above, w" ether or not your NRC license (s) to operate your nuclear power generating facility (ies) should be modified, suspended, or revoked.

Salem Unit Nc.1 OUALIFICATION CF CONTROL SYSTEMS As pert of a continuing review of the envirar. ental cualifications of Westinghouse supplied NSSS ecuipment, Wes:ingrcuse nas also found it r.ecessary to consider the interaction with non-safety grade systens.
This investigation has been conducted to deterrine if the performance of non-safety grade systems which may not be protected frcr an acverse environment could inpact the protective functicns perforned oy NSSS The NSSS control and protection systems were safety grade equipr.ent.

As a result of this review, several systems were identified which, if subjected to an adverse environment, could potentially lead to control These systems system operation which may impact protective functions.
are:
Steam generator power operated relief valve control system Pressurizer power operated relief valve contrcl system Main feedwater control system Automatic rod control system 77 // o s e 6 s D u P l=~
Pac.e 2 P S E-7 9-21 Eech of the above nentioned systens coulc potentially na'fu.ction if impacted by adverse environments due to a high energy line break inside or outside containnent.
In each case, a linited set of creaks, coupled with possible consequential control nalfunction in ar ad.erse directicn, of the above events could yield results which are rcre limiting than those presented in the plant Safety Analysis Reports.
In all cases, hcwever, the severity of the results can be linite; by c;erator acticns tcgetner witn operating characteristics of the safety systers.
We believe these systens identified do not constite;e a substantial safety hazard.
However, Westinghouse recommends you revien then to determine if any unreviewed safety cuestions or significant ceficiencies exist in your pl ant ( s).
To assist you in understanding these concerns, Westinghouse will hold a seminar in Pittsburgh on Thursday, September 6 at Westingnouse RIO Center, Building 701,.with all our operating pl ant custerers.
The seninar will address the potential irpect of these concerns for various plant designs and various licensing bases.
Please contact your fNSD Regional Service office to confirn ycur attendance at tha seninar.
We will provide additional detailr. concerr.ing the agenda and other meeting arrangements as they beco e available.
