- Present at the exit interview.
In addition to the above technical and supervisory personnel, the inspectors held discussions with various maintenance, operations, technical support and administrative members of the licensee's staff.
1.
Plant Status During the period of this inspection, the plant was in routine full power operation.
2.
Training The objective of this inspection effort was to ascertain whether the licensee's training program for non-licensed personnel was in conformance with the require-ments of the Technical Specifications and FSAR commitments.
The licensee's formal training program for non-licensed permanent employees consists of security indoctrination, radiation protection, plant and personnel safety, training in the emergency plan and quality assurance program. This training is supplemented by on-the-job training consisting of practical work and short seminars conducted by vendors.
Formal schools have been utilized for special instruction in certain technical areas.
The inspectors reviewed the training records of several non-licensed persons including an engineer, a health physics technician, a security guard, and a temporary employee.
These persons included new and long-term employees. The inspectors interviewed these persons to determine that the required training had been conducted as indicated.
In general, the employees considered the D

-3-training they had received to be effective in that they are able to do their jobs with proper regard for their own and public safety.
No itens of noncompliance or deviations were noted in this area of the ir,s c ecti on.
3.
Of'-Sas System Operations Tse insnectors reviewed the current status of the off-gas system to assess t.te 'icensee's actions and future plans to regain system reliability.
The 'icensee has had six fires or fast burns in the off-gas system since eart v y 1979. The most recent occurred on July 2, 9 and 23,1979. No a
system camage had occurred nor has any significant radioactivity been releasec as a result of these fires.
The cff-gas system is designed to 350 psi in order to withstand hydrogen explosions in the off-gas system.
In addition, the system is designed to isolate if high temperatures or pressures are sensed. To date, no system isolation has occurred as a result of these burns. The licensee believes that the catalyst in the recombiner is flaking and being carried over from the after condenser via the diluting stream to the third air ejector where it provides an ignition source for the hydrogen before it reaches the reccabiner.
The licensee has long-term plans in progress to redesign the off-gas system to improve system reliability. This will involve about two years.
In addition, short-term work is in progress to confirm the source of the problem and to attempt repair if possible.
The inspector will follow up on the licensee's activities in this area during future inspections.
4.
StartJp Testing The.
pose of this inspection effort was to verify the results of tests and procedures conducted in connection with the recent refueling. The inspector reviewed the following:
TIP Signal 'Jncertainty Test
.
Periodic Core Performance
.
Control Rod Operability Check
.
In addition, the inspectoi verified that changes in core performance para-neters as a result of refueling are within the limits established in the license and Technical Specifications.
No items of noncompliance or deviations were identified.

Plant Tour During the course of the inspection, the inspectors toured accessible areas of the facility to observe ongoing activities, verify system lineups and to inspect the general condition of the facility.
During a tour of the facility, the inspectors observed that several pro-cecuras found in various locations throughout the plant were not current revisions. These procedures (listed below) were not controlled copies; hewner. they were located at work locations where they would very likely be c ed if they were needed.

The inspectors expressed their concern that operating pro-cedures need strict control to ensure that only current precedures are used.
This item will be examined during a subsequent inspection.
6.
Follow Up on IE Bulletins The inspector performed follow up on the following IE Bulletins to determine that the licensee's station staff had received a copy of the Bulletins and had reviewed them for applicability.
The inspector reviewed the licensee's response for each Bulletin to determine that the response had been submitted in the time frame required and the information discussed in the licensee's reply was supported by facility records or a visual examination of the facility.
The licensee's corrective actions were reviewed to verify appropriateness.
