i 1.~ ' Sommary of generic deficiencies noted on oral exams:

A.) A majority of the candidates exhibited difficulty in determining,the magnitude,-direction and ti.me frame of changes to' major plant para-meters during transient condition Bl). In general, most candidates were weak in their ability to apply known theoretical knowledge in the areas of reactor theory and thermo-

_

!

dynamics'to practical applications, i.e., simple heat balance cal-culations, and transient ~ effects'of reactivit . Summary of generic deficiencies noted from grading of written exams: Candidates did not demonstrate an adequate level of knowledge-an understanding in the following areas:

(1) operating and emergency procedures (2) plant systems design (3) instrumentation and~ controls

..

~ ~ . Greater than 40*J of the candidates were extremely weak in theory of nuclear. power plant operation and thermodynamics associated with plant transient . Status of Previously Identified Items (Closed) Inspector Follow-up-Item (29/85-03-01) - Training material pro vided was inadequate for preparing R0/SRO examination ' -The training material provided on July 7,1985.for the upcoming R0/SRO examinations scheduled for October 1985 were reviewed by the operator licensi,ng staff and found to be satisfactory. Procedures and system descriptions were revised accordingly and were adequate for the pre-operation of the written and oral examination (Closed) Inspector Follow-up Items (29/85-03-02 and 85-03-03)

Procedures OP-3250, OP-3111 and OP-3001 were not revised to reflect current system and plant statu ~

,

The fc? lowing Procedures were reviewed by the Region I staff:

. OP-3001, "Large Loss of Load Without a Reactor Scram" Rev. 8, May 198 OP-3111, " Malfunction of Primary Pressure or Lovel Channels" Rev. 8, December 198 OP-3250, " Loss of a 120 Volt' A.C. Vital Bus".Rev.10, June 198 OP-3257, " Loss of No. 2 125 Volt DC Battery Bus Power" Rev. 4.
