Organization and Management Controls (IP 83750)
The inspector reviewed the licensee's organization and management
controls for the radiation protection program, including changes in the i
organizational structure and staffing, effectiveness of procedures and I
other management techniques used to implement these programs, and experience concerning self-identification and correction of program implementation weaknesses.
Audits are discussed in Section 10.
i l
Since previously reported (Inspection Report No. 254/88013; 265/88013),
I several organizational changes have occurred, including separation of the rad / chem department into separate health physics services and
!
chemistry departments.
The separation included permanently assigning i
rad / chem technicians to either health physics or chemistry positions.
'
There are currently 27 health physics technicians and 12 chemistry technicians.
The Health Physics Services (HPS) and Chemistry Supervisors report to the Assistant Superintendent of Technical Services.
The HPS supervisor is the former Rad / Chem Supervisor and the previous Station
Chemist is the Chemistry Supervisor.
Organization of the ALARA group is discussed in Section 9.
No adverse affects of the organizational changes were noted.
No violations or deviations were identified, 5.
External Exposure Control and Personal Dosimetry (IP 83750)
i
The inspector reviewed the licensee's external exposure control and
.
personal desimetry programs, including:
changes in the program to meet I
routine and outage needs; use of dosimetry; planning and preparation for maintenance and refueling tasks including ALARA considerations; and required records, reports, and notifications.
Changes made in the licensee's routine external exposure measurement and control program since last reported are discussed in Section 9 (ALARA).
For 1988, the station's total exposure was about 827 person-rem; the goal was 600 person-rem.
According to licensee documents, about 200 person-rem was received while performing unplanned corrective

maintenance and modifications including drywell ventilation work,
-
I weld overlays, anchor bolt work, and additional. in-service inspections.
The goal for 1989 is 845 person-rem based on projected work.
No exposures in excess of regulatory limits were identified.
No violations or deviations were identified.
6.
Internal Exposure Controls and Assessment (IP 83750)
The inspector reviewed selected aspects of the licensee's internal exposure control and assessment programs including:
determination whether engineering controls, respiratory equipment, and assessment of intakes meet regulatory requirements; and planning and preparation for maintenance and refueling tasks including ALARA considerations.
The licenste's program fcr controlling internal exposures include the use of protective clothing, respirators and equipment, and control of surface and airborne radioactivity. A selected review of RWPs, air activity surveys, and MPC-hour determinations for 1989 to date was made; no significant problems were noted.
RWPs appeared to adequately reflect the respiratory protection requirements for the job.
Whole body count data was selectively reviewed for counts performed during the period July 1988 through January 1989 on company and contractor personnel.
Followup counts, performed on persons who showed
<
elevated initial counts, were adequate to verify that the 40 MPC-hour control measure was not exceeded.
No problems were noted.-
l No violations or deviations were identified.
L 7.
Control of Radioactive Materials and Contamination (IP 83750)
The inspector reviewed the licensee's program for control of radioactive materials and contamination, including:
changes in instrumentation, equipment, and procedures; effectiveness of survey methods, practices, i
equipment, and procedures; effectiveness of methods of control of radioactive and contaminated materials; management techniques used to implement the program; and experience concerning self-identification and correction of program implementation weaknesses.
Audits are discussed in Section 10.
Control of radioactive materials in the mechanical maintenance shop, and response to guardhouse portal monitor alarms are discussed in Section 3.
The licensee has continued to improve appearance, housekeeping, and cleanliness in the turbine and auxiliary buildings; extent of contaminated areas h.ts been reduced.
The licensee has moved laundered protective clothing storage from the service building laundry room to the Units 1 and 2 trackway areas.
The laundry room is being altered to make room and provide shielding for a new laundry monitor which should be in use soon.

Dur'ing tours of ' radiological controlled areas of the' plant, the inspector
.
observed materials that could be used for personal decontamination near the Unit 2 trackway exit whole body friskers.
The inspector also noted that some Radiological Occurrence Reports (R0Rs). discussed events where station and contractor workers attempted to decontaminate themselves i
without-notifying RP.
The inspector did not observe any such recurrences during the inspection.
The friskers are observed by an RPT only part of the day shift.
The inspector found that the licensee was not using an optional feature.of the friskers which provides a printout of each alarm.
The inspector discussed with the licensee the desirability of using the.frisker alarm feature as a management quality assurance tool to compare the number of reported personal contamination events with the number of frisker alarms.
This matter was discussed at the exit meeting.
No violations or deviations were identified.
8.
Personal Contamination / Hot Particle Incidents (IP 83750)
The inspector reviewed personal contamination event (PCE) tracking and trending data for 1987, 1988, and 1989 to date.
There were 531 PCEs l
reported in 1987, 472 reported in 1988, and 13 events in 1989 as of
'
February 14.
The licensee expects a further decline in the number
,
of events because of implementation of enhanced routine facility
'
decontamination, cleaning, and housekeeping efforts; these efforts have been made easier by extensive floor, wall, and ceiling painting performed over the past three years.
The licensee continues to investigate personal contamination events'to identify cause and establish corrective i
measures to reduce the number of events.
'
During the period May through December 1988, twelve of the personal contamination events involved hot particles.
Isotopic analysis of recovered hot particles showed that cobalt-60 was the predominant isotope.
The largest particle was about'200 nanocuries, and the largest calculated skin dose was one rem.
The licensee's methods of identification, quantification, followup, and recording skin dose from hot particles appears good.
No violations or deviations were identified.
9.
Maintaining Occupational Exposures ALARA (IP 83750)
The inspector reviewed the licensee's program for maintaining occupational exposures ALARA including changes in ALARA policy and procedures.
The ALARA group now consists of an ALARA Coordinator, an RWP Coordinator, an ALARA Planner, and a REP / Air Sampling Coordinator; the latter two positions are filled with graduate health physicists.
The ALARA Coordinator reports to the Operations /ALARA Group Leader.
Also reporting to this group leader is the Contamination Controller.
The licensee has enhanced and expanded its job history files, and improved its method of L
establishing protective requirements for Type 1 and 2 RWPs.

Audits and Assessments (IP 83750)
The inspector reviewed records of onsite and offsite quality assurance audits conducted by the licensee during the period July through December 1988.
Extent of audits and adequacy and timeliness of corrective actions were reviewed.
One station and one offsite audit was conducted during the period; reviewed were various radiation protection and related subjects.
Identified during these audits were some incidents of failure to follow procedures and procedure content shortcomings:
the causes of the incidents and procedural shortcomings have since been corrected and the items considered closed by the auditors.
The corrective actions appear odequate.
A performance assessment of radiation protection and ALARA policies and practices was performed by a team of CECO health physicists from corporate, training, and other nuclear stations.
Seven items of possible improvement were identified during the assessment, none of which were noncompliance with regulatory requirements; actions in response to the improvement items are in process by the licensee.
The performance assessment was extensive and was conducted by qualified individuals.
No violations or deviations were identified.
11.
Exit Meeting (IP 30703)
{
The inspector met with licensee representatives (denoted in Section 1)
at the conclusion of the inspection on February 17, 1989, to discuss the scope of the inspection and the findings.
The inspectors also discussed the likely informational content of the inspection report regarding documents and processes reviewed by the inspector during the inspection.
The licensee did not identify any such documents / processes as proprietary.
The inspector discussed the desirability of using the whole body frisker alarm feature as a management tool.
The licensee stated that the matter would be considered (Section 7).
