.a ReDort of Interview John Michael Puckett, Director, Enforcement and Investigative Coordination Start, Region II, U.S. Nuclear Regulatory Comr.ission (NRC), was interviewed concerning nis knowledge of the discrepancies in the Licensed Operator Train-ing Program (LOTP) at Grand Gulf Nuclear Station (GGNS) relative to Region II enforcement actions. He provided the following information:
Following the February 15-17, 1983, training assessment by Region II of LOTP at GGNS, there was an early to mid-March meeting held at Region 11 in order to discuss the findings of the assessment as well as any possible enforcement actions to be taken by Region II in this matter. At the meeting the issue was raised concerning a possible Material False Statement (MFS) made by Mississippi Power and Light (MP&L) in connection with the discrepancies in "
LOTP. Specifically, the discrepancies were apparent missing or misplaced documentat1on. It was . resolved during the neeting that there was not enough information available at that time to make a determination as to whether or not MP&L committed an MFS. ~ Also, it was resolved that the discrepancies noted during the assessment would be pursued as an unresolved inspection item pending further inferr.ation. The Region II personnel in attendance at that meetino were then Reactor' Projects Branch (RPB , tvision o neactor roj ects .
RPB, David Verrelli, Chief, RPB,
.rm RPSIA, and himself. He noted that Operatinns Branch, Division o neactor ety, and others wno ne recall were also in attendance at that meeting.
A follow up inspection / assessment of operator training at GGNS was conducted by Region II on August 15-September 1, 1953. the findings of the follow up inspection indicated that the discrepancies concerning the missing or mis-placed documentation may have been more than just a paper problem in that some of the reactor operators may not have received all of the training which MP&L had cent.itted to in the Final Safety Analysis Report (FSAR). Additionally, from the end of August 1983 through September 20, 1983, there were a number of discussions and inforration gathering efforts by Region II to further determine the extent of the problem with LOTP at GGNS. Because of these efforts and discussions, Region 11 concluded that .the problems associated with the operator training at GGNS were greater than first believed.
~
Consequently, on September *20,1953, there was an enforcement panel convened within Region 11 to evaluate the available information and make a determina- He tion as to what enforcement action Region 11 should take in this matter.

. 4 plant. The mejority of the operators were found competent and they had already been lic,ensed by NRC, therefore, a suspension or revocation of their licenses was not warranted on the basis of discrepancies in their training program. The conritment by MP&L to recertify LOTP was confirned by Region II in a December 5,1983, letter to MP&L.
With respect to language in the letter stating " prior to exceeding 55 pewer,"
he agreed that obviously the licensee could not exceed five percent power with a low power license. It is possible that the underlying purposes for not using language in the letter stating that the licensee shall not operate were (1) If the reactor was not allowed to operate, the reactor startup scurces would decay to a level which would not permit reactor startup without replacement of the sources. To replace the sources would be a very costly procedure as well as a very delicate one from i a health and safety aspect.
(2) By allowing the reactor to operate at less than five percent power,
- low power testing could be continued.
Moreover, the magnitude of:the problems associated with the operator training at GGNS became known to Region II over an extended period of time and discrete events did not occur in that regard enabling Region Il to take actions based solely on one event or circumstance.
