Webelieve that the BUR Emergency Procedure Guidelines provide a basis fora significant improvement over current emergency operating procedures.Although the guidelines are not complete (combustible gas control andsecondary containment control guidelines are not yet included) and theenclosed Safety Evaluation Report requires a few changes to theguidelines, we find the guidelines with the NRC proposed changes to beacceptable. We suggest that implementation of the guidelines proceed intwo steps:(1) Preparation of plant specific procedures which in general conformto the Emergency Procedure Guidelines referenced above andimplementation of these procedures as outlined in Supplement 1 toNUREG-0737, transmitted by Generic Letter No. 82-33 dated December17, 1982.(2) Preparation of supplements to the Guidelines which cover changes,new equipment, or new knowledge and incorporation of thesesupplements into plant specific procedures.Step (1) refers to the Guidelines referenced above and discussed in theenclosed SER. Step (2) refers to Guideline updates which will begenerated as a matter of routine after the plant specific procedureshave been put in place. Although Step (2) includes combustible gascontrol and secondary containment control guidelines which are yet to bedeveloped, it is essentially a maintenance function.During our review, we identified several steps In the guidelines whichrequire minor changes. These are identified in the enclosed SER. Weask that you address these items during the implementation of Step (1).We also note that the guidelines are written for the procedure writers,not control room operators, and therefore preparation and implementationof procedures will require additional Human Factors input.8302080301 ../ IOPFICK11.SURNAM -............................................. ..._ _........................... ...._..........................._...._.........................._..._............................................. .......... ............ .... ,,............................ ........................... ............ .......................... ............ ........................DATK)I....................... .... ........................ .......................... .....

Therefore, we have requested in the enclosed letter thatthe BWR Owners Group provide a description of the program for futurechanges or supplements to the guidelines.As discussed in the enclosed SER, we find the actions specified in theEmergency Procedure Guidelines to be generally correct and appropriateand within the operator's capability. The combination of all emergencyactions into two guidelines and seven contingencies greatly simplifiesthe emergency instructions. In addition, the use of symptoms rather thanevents as bases for actions, eliminates errors resulting from incorrectdiagnosis of events, and addresses mutilple failures and operatorerrors. We therefore find the guidelines acceptable for implementation.
