Ins ection on Januar 25 - 29 1988 Re ort No. 50-410/88-03
of Nine Mile Point 2 (NMP-2) Licensed Operator Training (Requalification Training) to evaluate the effectiveness of the licensee's program.
The focus of the inspection was to determine whether Operator Training could have prevented or mitigated the Unusual Event that occurred at Nine Mile Point 2 on January 20, 1988 (see section 2.3 of report).
The inspection consisted of reviews of training records and training program procedures, observations of simulator training sessions and interviews with licensed operators.
Results:
No deficiencies were found with the licensee's Licensed Operator Training Program.
No correlations were found between individual training deficiencies and operator performance during the Unusual Event.
Results of the inspection indicated that training could not have prevented or mitigated the Unusual Event.

"Denotes those present at the exit meeting conducted on January 29, 1988.
2.0 PROGRAM AREAS INSPECTED 2. 1 Licensed 0 erator Trainin Procedure NMP Training Procedure NTP-11 was reviewed to ensure that it met the requirements of 10CFR 55.59(c) for the requalification program.
Implementation of NTP-11 was discussed with several training instructors and twenty (20) licensed operator training files were reviewed to determine compliance with NTP-ll.
CFR 55.59(a)(1)
requires that each licensed operator successfully complete a requalification program and 55.59(c) defines the requalification program requirements.
The NRC had a previous concern that annual examination results were being used to exempt operators from attendance at portions of requal training.
This exemption from lecture attendance did not meet the intent of 10 CFR 55.59.
NTP-ll was revised in September 1987 to incorporate the requirements for continuing training in accordance with 10 CFR 55 (effective May 26, 1987). 'he policy of testing out is no longer in effect.
Attendance at all lectures is required for all licensed operators and the program requires that any lectures that are missed are made up prior to the completion of the annual requalification period.
All licensed operators, including tr aining instructors, are required to take an annual operating examination and a comprehensive written examination during each requalification program perio The Nine Mile Point 2 Licensed Operator Training Program is conducted continuously over a two year period and therefore meets the schedule requirements of 10 CFR 55.59(c)(1).
The program ensures that the lecture subject material and control manipulation requirements of
CFR 55.59(c)(2)
and (3) are met by every licensed operator.
The annual operating examinations and biennial written examinations meet the evaluation requirements of 10 CFR 55.59(c)(4).
Based on discussions with the training instructors, it was determined that the changes made to the methods of documentation of requalification training with the latest revision to NTP-11 meet the requirements of 10CFR 55.59(c)(5).
The new methods of documentation of requalification training became effective when NNP-2 commenced Cycle 1 of the present requalificaiton program in Jan'uary 1988, therefore the training files for those operators that had not attended Cycle 1 of requal training were not up to date.
No deficiencies were found in the training files for those operators that hact attended Cycle 1 prior to the inspection.
It was determined that the NMP-2 Licensed Operator Training Program as defined by NTP-11 meets the requirements of 10CFR 55.59(c)
and that requalification training is being conducted in accordance with NTP-11.
~ 22 Simulator Trainin The inspector observed two (2) sessions of requalification training using the plant specific simulator and discussed simulator training methods with the simulator instructor and eight (8) licensed operators.
Instructor preparation was good, lesson plans were complete and adhered to during the training sessions.
Both normal and abnormal evolutions were covered and all students were actively involved.
The evolutions were discussed thoroughly and student participation was encouraged.
The students did not hesitate to ask questions and their questions were answered knowledgably by the simulator instructor.
System drawings were used to provide a more in depth under standing of the operations being performed.
(Ability to use the system drawings was recognized as a generic strength during the licensing examinations administered during the week of January 25, 1988.)
2.3 Januar
1988 Unusual Event On January 20, 1988 an Unusual Event occurred at Nine Mile Point 2.
A Loss of Instrument Air resulted in a feedwater transient and a
reactor scram.
During recovery from the transient, the reactor was overfi lied to a level above the Main Steam Line Based on review of training files and interviews with operators involved in the Unusual Event, no correlations were found between training deficiencies and operator performance during the event.
The interviews indicated that training could not have prevented or mitigated the event.
The operators felt that the vessel overfill problem was due to the Feedwater Flow Control Valves not acting as designed and complicated by the large number of people in the Control Room distracting the Station Shift Supervisor who was directing restoration of water level.
2.4 0 erator Interviews Training quality and effectiveness'was discussed with eigh't (8)
licensed operators.
Host operators felt that requalification training had improved over the last year, but that meeting the requirements of INPO and 10CFR55 for preparation and documentation of training detracted from the effectiveness of that training in regards to job performance activities.
3. 0 EXIT INTERVIEW The inspection scope and findings as detailed in this report were summarized on January 29, 1988 during a combined Operator Licensing/
Training Program Inspection exit interview.
(See paragraph 1.0 for attendees.)
The inspector determined that no proprietary information was utilized during the inspectio
