REFERENCE:

(a) Letter from Mr. James 11. Joyner (NRC) to Mr. George C. Creel (BG&E). Review of Calvert Cliffs Nuclear Power Plant Emergency Action levels (EALs), dated February 12,1991 (b) NRC Combined Inspection Report Nos. 50 317N004 and 50 318S0 04 Gentlemem Reference (a) discusses the results of Nuclear Regulatory Commission sttif review of Revision 14, Change 3 to the Emergency Classification and Action Level Scheme for Calvert Cliffs Nuclear Power Plant. This review concluded that the Emergency Action Level (EAL) scheme has been % proved, but that additional changes are needed to meet the guidance of NUREG 0654. The letter requested a response to staff review comments and a schedule for implementing further changes to the EAL scheme.

it has been BG&Es consistent intent to use the guidance of NUREG 0654 in defining those conditions which should initiate EAL declarations. We have been equally attentive in attempting to insert that guidance into our EALs in the form of dennitions that are clear-cut and straightfonvard for application by our operat;ng staif. To this end, we have tied EAI. declarations to our Emergency or Abnormal Operating Procedures (EOP/AOP) wherever possible. Since these do not fit identically with the wording of NUREG4)654, we have attempted to identify equivalent conditions as nearly as possible while still complying with the intent and spirit of NUREG 0651, We have carefully considered your previous comments from Reference (b) in evaluating these interpretations, and have

! resolved most of your noted concerns. Your most recent letter addresses some remaining items. We l have reviewed these and our comments are provided in Attachment (1). Additionally, our implementation schedule is included in Attachment (2). ,

1 As discussed earlier this month with Mr. Jim Wiggins of the Region 1 office, BG&E Emergency i l

Planning personnel will discuss the specifics of the EAL revision with you at your convenience in l King of Prussia.
