R. M. Keller (USNRC) The following generic deficiency was noted on the operating examination This information is being provided to aid the licensee in upgrading license and requalification training programs. No licensee response is require Communication between the candidates during the simulator portion of the examinations was at two extremes. The operators were either very conscientious with correct orders and repeat backs, or very poor with vague orders and generic responses. Examples of the poor communications are: " bring it [the turbine generator] up fast", "How you doing?" or
"Okay" [in response to " bring it up fast"]. The following is a summary of generic deficiencies noted from the grading of the written examinations. This information is being provided to aid the licensee in upgrading license and requalification training program No licensee response is required.

4 Summary of comments made at the Exit Interview: The NRC summarized the examinations administered during the week and discussed the one generic weakness identified during the operating examination See paragraph 1 above, The NRC expressed concerns with respect to how the Emergency Operating Procedures (EOPs) were used durin'g the simulator ,
examinations. Th6 concerns are:
(1) The Control Room Supervisor (CRS) does not appear to adequately control the plant during the implementation of the E0P The CRS does not direct the completion of individual steps but instead directs that sections be completed. Frequently, two or three sections at a time would be. assigned to one of the board operator During one of the scenarios, six sections were simultaneously assigned to the secondary operator, and there was no direction given by the CRS as to the priority of the sections. When asked by their examiner, the SRO candidates (while in the position of the CRS) were unable to show exactly where they were in the E0P !
(2) When the board operators would report back that a section was completed, the CRS denoted completion of the section by putting an "X" in the procedure manual. This method of tracking could
, lead to confusion the next time that procedure was use (3) Because the board operators are directed to do a section of a procedure vice a specific step, they must carry the procedure manuals with the This process is very cumbersome for the operators and could lead to a manual being dropped on the panels, possibly causing the status of an emergency ccmponent to be change . The written examinations were reviewed by the utility and discussed with the examiners after all candidates had completed the examination on October 27, 1987. The facility's comments (Attachment 3) and the NRC resolution (Attachment 4) are enclosed. The following facility individuals reviewed the examinations:
