- Attended exit interview Exit Interview The inspection scope and findings were summarized on May 22, 1981 with those persons indicated in paragraph 1 above.
The inspectors discussed the status of the 'Inspector Follow-up Items, Significant Weaknesses and Vi'olations from the Health Physics Appraisal conducted May 5-16, 1980 and other open items and enforcement matters from previous inspections.
Two open items concerning replacement of the containment purge exhaust filters and the facility ventilation system balance evaluation were discussed at length.
The inspectors stated that although the response to the Health Physics Appraisal indicated that action had been completed or at least initiated on these matters, it appeared sufficient measures to correct these weaknesses had not been promptly taken.
The Acting Plant Manager-Nuclear stated that the containment purge exhaust filters will be replaced immediately, priority will be re'established for the ventilation balance evaluation and the necessary effort will be expended to adequately closed out the remaining open items.
On May 28, 1981, the licensee was informed that failure to replace the containment purge exhaust filters as agreed to in response to the Health Physics Appraisal would be considered a deviation from a commitment to the NR ~ 0

Steam Generator Replacement Project The inspector examined the licensee's preparations for the steam generator replacement outage.
Although unable to devote sufficient time for a thorough'evaluation of the project, the inspector con-cluded that it appeared that adequate supplies of protective clothing and portable survey instruments were available, that the change area appeared to be adequate and that the personnel contamination surveillance and exposure control programs appeared to be satisfactory.
During a tour of the Unit 3 Containment Building, the inspector noted that, air was flowing out of the opened equipment hatch.
The inspector stated that the flow of air should not be from contaminated or potentially contaminated areas to clean or less contaminated
'ocations.
A licensee repesentative stated that in response to IE Bulletin 79-02, the containment purge valves had been throttled back to approximately 15% of rated exhaust and that it appeared no restrictions had been placed on the supply fans.
If two supply fans and two exhaust fans were simultaneously in operation and both the personnel and equipment hatchs were open, air flows'ut of the equipment hatch.
Licensee management agreed to evaluate this matter.
The inspector stated that this item will be reviewed during future inspection (250-251/81-12-03}.
Potential Overexposure A routine monthly TLD readout on June 2, 1980, indicated that a
worker had received 5.8 Rem for the month of May.
Combined with previous exposure received during the second calendar quarter of 1980, it appeared that the worker had received 7.4 Rem since April 1, 1980.
The NRC was informed of this event by telephone on June 2, 1980.
During this inspection, the inspector reviewed the exposure evaluation report prepared by the licensee.
This report included descriptions of work activities, interviews with accompanying personnel, and comparisons with pocket dosimeter readings and other personnel exposures working with the individual allegedly overex-posure.
Based on the information provided in the report and discussions with licensee representatives, the inspector concluded that an exposure of 2. 14 Rem for the second calendar quarter of 1980 assessed by the licensee appeared to be appropriat e
