Assuranc The assessment consists of eight modules which are grouped to address various program area The eight areas include, contamination controls, radiation protection organization and

' 6cministration, external exposure control, internal radiation exposure,

' control of solid radioactive waste, work control, and instrumentation and equipmen ,

specific areas within Within each module are sub-modules which address '

the aforementioned general areas. An average

' rating is determined for each general area based on the results of each specific area finding. The numbers are then pooled to produce an everall rating for the program. The findings for each specific area ,

'

are then passed to the appropriate supervisor for corrective action I Within the report, no area received a rating below the acceptable level (rating 2.0). There were a number of specific area ratings that borderlined the acceptable / unsatisfactory level (rating 2.5),

inspectors discussed with the RP Superintendent the results of this evaluation and inquired about corrective actions for those areas rated as borderline or unsatisfactor Based on these discussions, inspectors determined that timely and appropriate corrective actions

, were being taken for the items of concern.

Training and Qualifications 10 CFR 19.12 requires the licensee to instruct all individuals working or frequenting any portions of the restricted areas in the health protection aspects associated with exposure to radioactive material or radiation, in precautions or procedures to minimize exposure, and in the purpose and function of protection devices employed, applicable i provisions of the Commission Regulations, individual responsibilities and the availability of radiation exposure dat The inspectors reviewed changes in the licensee's training program, !

policies, and goals relating to the radiation protection program and discussed the changes with licensee representatives. The inspectors verified that the changes should not adversely affect the licensee's progra The inspectors discussed the Health Physics Technician Development 4 Program (HPTCP) with the program's lead instructor. The program currently has an enrollment of 14 individual The curriculum consists of seven steps, each step contains four to six modules which address the subject matter for the step. While performing self-study and tasks required for each module, the student is under the supervision of an experienced HP technician, who reports his progress to a representative from the training program. Completion of module in-plant tasks are performance tested under the supervision of a HPTDP instructor. For steps which focus on a specific RP program area (e.g. count room, dosimetry, ALARA, etc.), the student is assigned to that particular laboratory or office. A strong effort is made not to

Internal Exposure Control (Whole Body Counting System)

'

The licensee has recently amended its procedure for calibration of their two whole body counters (ND standup counter and a chair counter.)

As detailed in a prior inspection (IR 90-25), the licensee did not perform annual calibrations of the whole body counting systems. Full calibrations were performed only in the event that the counters failed a QC test. Cognizant personnel stated that Procedure HP-5.2B.62 "Whole Body Counter Calibration Standup & Chair /ND9900," dated August 10, 1990, would be amended to include a statement concerning the annual calibration of the whole body counting systems. The re stipulations will remain the same for QC test failures,quirements however and the whole body counters will now be regularly calibrated on an annual basi As the inspectors were preparing to exit the site, it was observed that the control quality whole body counters could not be calibrated to meet procedural limit Further investigation by the licensee into the problem revealed the background count rates were significantly elevated throughout the entire gansna ray energy spectrum. The licensee indicated that the problem a inversion layers in the area. ppeared These to be due layers toto tend meteorological

The dosimetry technician requested the inspectors to provide samples for urinalysis. The collection of urinalysis samples is currently a non-proceduralized contingency in the event the whole body countino sys ums are inoperable. Discussions with licensee management indicated that this backup plan would be formally added to the whole body counting procedures. There were no positive results indicated by the urinalysi . .

! Surveys. Monitoring, and Control of Radioactive Material and Contamination

10 CFR 20.201(b requires each licensee to make or cause to be made such surveys as)(1) may be necessary for the licensee to the regulations and (2) are reasonable under the circumstances to evaluate the extent of radioactive hazards that may be presen The inspectors reviewed the plant procedures which established the licensee's radiological survey and monitoring program and verified that the procedures were consistent with regulations, Technical Specifications, and good health physics practice Inspectors reviewed the licensee's shift log of regular surveys performed on a daily, weekly, monthly, and quarterly basis. All ;

'

surveys were documented as being performed in the required time fram A selected group of surveys were reviewed for proper documentation and supervisory review as required by procedures. All surveys reviewed were in order and had been reviewed by appropriate supervisors in a timely manne Inspectors discussed the contamination control program with licensee representative the 89,500 squareDecontamination feet of the RCA continues with 11,495 of contaminated at the end of 1990. Licensee representatives stated that areas of the auxiliary building. plans are in place to continue reclaiming Inspectors reviewed the Leak and ,

Contaminated Area Tracking Update Report (LACAT) for 1991. This report lists the areas in need of deconning, collective dose estimates to decon, and the daily maintenance dose expenditure for the areas while contaminate It also outlines priority areas for reclamatio The licensee plans to reclaim approximately 3,000 square feet of contaminated area in 199 Program for Maintaining Exposures As Low As Reasonably Achievable (ALARA)

10 CFR 20.1(c) states that persons engaged in activities under licenses issued by the NRC should make every reasonable effort to maintain radiation exposures a low as reasonably achievable. The recomended elements of an ALARA program are contained in Regulatory Guide 8.8, Information Relevant to Ensuring that Occupational Radiation Exposure at Nuclear Power Stations will be ALARA, and Regulatory Guide 8.10, Operating Philosophy for Maintaining Occupational Radiation Exposures ALAR The licensee's ALARA program continues to be an aggressive element within the radiation protection progra The inspectors noted the continued involvement of corporate management with ALARA through the implementation of the station's Five Year Dose Reduction Plan and funding support described in the 1991 Business Pla _

. -. -.

. .

The licensee's ALARA program has continued to implement new dose reduction techniques which include; telemetry for dose meters, staggering of dose allotments for workers on a particular job depending on the radiation field in the exact area the worker will be performing the task, ALARA responsibility being passed to other departments (Operations and Maintenance and others) via the respective departmental ALARA coordinators, and ALARA training incorporated in routine quarterly training of maintenance and site services personne Continued usage of the Videodisc Information Management System (VIMS)

has also contributed to further operational dose reductio The ALARA Coordinator has recently enhanced the VIMS to include component mark numbers and indicate low dose waiting areas. The use of the system is expanding and maintenance has identified the need for two VIMS within their departmen Inspectors attended the monthly ALARA Comittee meeting on March 28, 1991, which reviewed recent ALARA suggestions and RWPs for higher dose jobs during the upcoming Unit 2 outage. The comittee is comprised of the respective departmental ALARA coordinators, an assistant plant manager, supervisors from various HP sections, and the HP Superintenden The ALARA suggestions were determirs i to be substantive and addressed specific dose problems which provided for changes that would reduce dose through physical changes or procedural technique Items approved while the inspectors were in attendance j included:

Color coding of resin discharge piping to avoid confusion during pre and post surveys to reduce time in the are *

Provision for a low dose work area in the radiologically controlled areas (RCAs) to allow workers to bring valves and other components

out of a high dose area while performing repairs and calibrations before installatio Install remote radiation monitors on skimmer filter housings with readout in a low dose area to inform HP technicians of increase in filter dose rate *

Purchase of peristaltic pumps that use tygon tubing to replace steel pumps for draining liquid waste. The tubing pump would not become contaminated as would the steel pump thus minimizing radwaste and spreadable contaminatio During the RWP portion of the meeting, inspectors noted that the committee thoroughly briefed the foreman for each particular job and emphasized the radiological hazards and pointed out any relevant dose reduction techniques. The committee responded to concerns about the jobs expressed by the foremen. Of particular note was a suggestion made by an ironwork foreman who stated that he felt doses for his portion of a job could be reduced if filters were changed prior to his entry into the are Although the dose reduction for this effort was

These pumps assist dose reduction by ,

l the use of inherent ALARA design features. Breakdown and refitting can be accomplished in about one-third the time required for standard pumps as the pumps are mounted on a bed that can be rotated to facilitate maintenanc Usually only four wrenches are required for total disassembly. Over time for dose intense maintenance, this advantage could lead to significant dose savings at the facilit The inspectors determined all systems reviewed met requirements of modules 83527 and 8352 No violations or deviations were identifie .
