Results: No violations of NRC requirements were identified. Overall, the licensee's radiatioa protection program continues to improve.. The department
has supplemented its staff and is maintaining adequate personnel levels to ensure the health and safety of the general workforce and the public.
The l department has made improvements in preparing for the upcoming dual unit outage which should improve the operational performance of the RP department and the general station workforce during the outage.

Oroanizational Channes (IP 83750) l The inspectors reviewed changes to staffing and organization to the RP ' department which had occurred since the last inspection (IR 50-295/93013 ' (DRSS); 50-304/93013(DRSS)). The RP department had supplemented its staff with two professional health physicists; one each to the operational and technical staffs. One of the individuals has had
previous experience with the corporate group, and the other is recently I out of college with no previous commercial power plant experience. The inspector noted that the addition of these personnel has completed the replacement of vacancies which have occurred in recent months.
Overall, the RP department remained well staffed with technically competent and experienced personnel.
No violations of NRC requirements were identified.
3.
Audits and Annraisals (IP 83750) The inspectors reviewed the results of recently completed station i quality verification audits and field monitoring reports. Two audits reviewed, #93-01 and #93-02, were found to contain good findings and I l were thorough in nature. The response dates for many of the findings were still pending; however, all findings are tracked by the licensee's ! internal monitoring system and will be reviewed for completion during future inspections.
l <
The field monitoring program involves the observance of actual
activities in the field to identify any adverse trends. Many of the observations reviewed were of RP personnel performing assigned tasks.
No problems were noted with the performance of RP personnel. A few observations noted whole body friskers found inoperable at the auxiliary building exit point and in general areas within the auxiliary building.
The inspector also oL_cved several of the whole body friskers inoperable during the course of the inspection. The inspector held discussions with station management to determine the reason why the friskers were inoperable for lengthy periods of time. The station currently does not assign an instrument maintenance worker routinely to RP to assist in the repair of the whole body friskers.
Subsequent conversations with the Superintendent of Maintenance indicated that the station would consider assigning instrument maintenance technicians for long periods of time to the RP department to better address the frequent , inoperability of the whole body friskers.
No violations of NRC requirements were identified.
4.
Radiation Surveys and Contamination Control Proaram (IP 83750) The station had recorded 124 personnel contamination events (PCEs) for the year at the time of the inspection.
PCEs are trending about as expected for the year, and improvements have been noted in the frequency of events as compared to 1992.
The station recently changed its survey frequency program for various areas throughout the plant. The inspector reviewed the program changes which extended the frequency time for most weekly and monthly surveys.
The new program will extend some infrequently entered areas to a quarterly schedule, and special considerations were included for non-outage and outage times. The inspector discussed with RP staff the changes and noted that an effort was being attempted to perform more thorough surveys due to the lengthening of the frequency requirement.
- The inspector noted no problems with these changes but will monitor this area during future inspections.
No violations of NRC requirements were identified.
5.
Internal Exposure Controls (IP 83750) The inspector reviewed the licensee's program for respiratory protection. All respirators ready for use appeared to be in good working order and in good condition. The RP department has bar coded each respirator for use with their access control database for reference information in the event of an unexpected intake. The database can provide information on the worker entering the radiological controlled area and indicate which respirator the individual checked out for use on a given job. Overall, the inspector noted no significant changes in the licensee's program and found the program well managed and controlled.
No violations of NRC requirements were identified.
. . 6.
External Exposure Controls (IP 83750) f The inspector reviewed selected standing and special Radiation Work ! Permits (RWPs) for appropriateness of the radiation protection (RP) requirements based on work scope, location, and radiological conditions.
All RWPs reviewed conveyed accurate information regarding radiological , information based on recent survey results and had undergone appropriate ' supervisory review.
The inspector also observed during plant tours that individuals in the ! radiologically controlled area were properly wearing primary and l secondary dosimetry.
l ' No violations of NRC requirements were identified.
7.
Maintainina Occuo:._ Mnal Exposures ALARA (IP 83750) , l The inspector rev;.a year to date exposure totals for the station and i preliminary planning which had begun for the upcoming dual unit outage.
l The station had recorded 160 person-rem for the year at the time of the inspection.
This number was trending as planned for exposure totals ' estimated for the year.
The RP department had begun processing radiation work requests for RWP development. Approximately 650 requests had been received at the time of the inspection and RP personnel were establishing dose estimates for ! the various jobs to be performed. The RP department had also initiated
activity reviews of various tasks which were to be completed by RP personnel prior to the outage.
Each of the RP groups (operational and technical) had assembled an activities list which detailed respective areas to address, completion dates, and responsible individuals.
Examples of the operational task lists include HP schedules, RWP development, source term reduction activities, contractor radiation protection technician selection and assignments. The technical staff performed a breakdown of available equipment and assigned key personnel to perform installation and monitoring of the performance of this equipment during the outage. The inspector noted that this early review of activities for the outage was an improvement in the RP department's preparation for outages and should assist in providing timely and organized outage control. The inspector discussed at the exit meeting (Section 9) that a thorough review of broad scope outage planning and activities to be performed would be reviewed during the next routine inspection.
No violations of NRC requirements were identified.
8.
General Station Tours The inspector performed several walkdowns of the auxiliary and fuel buildings during the course of the inspection. The inspector noted that the general radiological housekeeping of the auxiliary building was good for the work in progress at the time of the inspection. The inspector-
l
- .
h also performed independent radiation and contamination surveys of areas within the auxiliary building. All radiation measurements were ' consistent with documented surveys. All instrumentation (meters, air monitors, etc.) observed during the tours were in good working order and in current calibration.
No violations of NRC requirements were identified.
9.
Exit Meetino The scope and findings of the inspection were discussed with licensee representatives (Section 1) at the conclusion of the inspection on August 6, 1993. Specific items discussed during the exit meeting are summarized below.
Licensee representatives did not identify any documents or processes reviewed during the inspection as proprietary.
Overall assessment that the RP program is continuing to improve.
! All documents and associated material reviewed in the topical areas were complete and accurate.
The issue of whole body friskers being frequently out-of-service and potential ways the licensee plans to address the problem.
