REPORT DETAILS
RADIATION SAFETY
Cornerstone: Occupational Radiation Safety (OS)
2OS1 Access Control to Radiologically Significant Areas (71121.01)
.1 Plant Walkdowns, Radiological Boundary Verifications, and Radiation Work Permit
Reviews
a. Inspection Scope
The inspectors conducted walkdowns of the radiologically protected area to verify the adequacy of radiological area boundaries and postings. Specifically, the inspectors walked down radiologically significant work area boundaries (radiation, high and locked high radiation areas) in the Auxiliary Building, radwaste area, spent fuel pool/refuel floor, as well as the Unit 2 Containment. The inspectors performed confirmatory radiation surveys in selected portions of these areas to verify that these areas were properly posted and controlled in accordance with 10 CFR Part 20, licensee procedures, and Technical Specifications. The inspectors also examined the radiological conditions of work areas within those radiation, high and locked high radiation areas to assess the adequacy of licensee implemented contamination controls. Additionally, the inspectors reviewed radiation work permits (RWPs) for general tours, access to locked high radiation areas (LHRAs) for work on spent fuel pool (SFP) demineralizers, drumming room clean-up activities, an at power entry into Unit 1 for work on a reactor coolant pump; and for another at power entry into Unit 2 for work on the no.1 safety injection (SI) accumulator. The RWPs were evaluated for protective clothing requirements, respiratory protection concerns, electronic dosimetry alarm set points, use of remote telemetry dosimetry, radiation protection (RP) hold points, and As-Low-As-Is-Reasonably-Achievable (ALARA) considerations, to verify that work instructions and controls had been adequately specified and that electronic dosimeter set points were in conformity with survey results.
b. Findings
No findings of significance were identified.
.2 Job-In-Progress Reviews, Observations of Radiation Worker Performance, and
Radiation Protection Technician Proficiency
a. Inspection Scope
The inspectors observed selected portions of the following radiologically significant work activities performed during the inspection and evaluated the licensees use of radiological controls:
- Unit 2, No.1 SI accumulator level indicator repair; and
- Preparations for SFP demineralizer work The inspectors reviewed the pre-job briefing package for the work evolutions, reviewed the radiological requirements for the activities and assessed the licensees performance with respect to those requirements. The inspectors reviewed survey records, including radiation, contamination, and airborne surveys, to verify that appropriate radiological controls were effectively utilized. The inspectors also reviewed in-process surveys and applicable postings and barricades to verify their accuracy. The inspectors observed radiation protection technician (RPT) and worker performance during the work evolution at the job sites to verify that the technicians and workers were aware of the significance of the radiological conditions in their workplace and RWP controls/limits, and that they were performing adequately given the radiological hazards present and the level of their training.
b. Findings
No findings of significance were identified.
.3 Identification and Resolution of Problems
a. Inspection Scope
The inspectors reviewed licensee Condition Reports (CRs) written since the last inspection (July 2002) to the date of the current inspection, which focused on access control to radiologically significant areas (i.e., problems concerning activities in HRAs, radiation protection technicians performance, and radiation worker practices). The inspectors also reviewed the recently revised High, Locked High, and Very High Radiation Area Access procedure, which addressed new requirements for specific locking devices for these areas. The inspectors reviewed these documents to assess the licensees ability to identify repetitive problems, contributing causes, and the extent of conditions, and then implement corrective actions in order to achieve lasting results.
b. Findings
No findings of significance were identified.
2OS3 Radiation Monitoring Instrumentation (71121.03)
.1 Walkdowns of Radiation Monitoring Instrumentation
a. Inspection Scope
The inspectors reviewed the Updated Final Safety Analysis Report (UFSAR) and performed walkdowns of continuous air monitors in the Auxiliary Building, radwaste area, spent fuel pool/refuel floor, radioactive material building areas, and one area radiation monitor (ARM) in the Unit 2 Containment. Additionally, the inspectors examined a representative number of portable radiation survey instruments staged throughout the licensees facility to verify that those instruments had current calibrations, were operable, and in good physical condition. The inspectors also reviewed the status of repair or troubleshooting activities associated with selected radiation monitoring instruments (i.e. small article monitors and portal monitors that had work request tags)to verify that instrumentation problems were being addressed in an appropriate and timely manner.
b. Findings
No findings of significance were identified.
.2 Calibration, Operability, and Alarm Set Points of Radiation Monitoring Instrumentation
a. Inspection Scope
The inspectors examined radiological instrumentation associated with monitoring transient high and/or very high radiation areas to verify that the instrumentation was operating consistent with industry standards and in accordance with station procedures.
Specifically, the inspectors assessed the operability of the following instrumentation:
- Unit 2, In-Core Instrumentation Room ARM The inspectors reviewed the licensees alarm set point for this specific ARM to verify that the set point was established consistent with the UFSAR, Technical Specifications, and the stations Emergency Plan.
The inspectors discussed surveillance practices with licensee personnel and reviewed calender year (CY) 2001 - 2002 calibration records and procedures for selected radiation monitors used for assessment of internal exposure. The inspectors also reviewed calibration records and procedures for those instruments utilized for surveys of personnel and equipment prior to egress from the radiologically controlled area (RCA).
These instruments included:
- AMS-4 Air Monitoring System;
- APTEC PMW-3 Personnel Monitor; and
- Gamma 40/60 Portal Monitor.
Additionally, the alarm set-points for these instruments were reviewed to verify that they were established at levels consistent with industry standards and regulatory guidance provided in Health Physics Positions no. 72 and no. 250 of NUREG/CR-5569.
The inspectors evaluated the calibration procedures and CY 2001 - 2002 calibration records for selected portable radiation survey instruments to verify that the had been properly calibrated consistent with the licensees procedures. Specifically, the inspectors reviewed the calibrations of the following instruments:
- Emergency Plan designated RO-7 ion chamber; and
- Smart Radiation Monitor general area dose rate meter.
The inspectors also assessed periodic performance tests (PPTs) completed for selected portable radiation survey instruments to verify that the had been tested consistent with the licensees procedures. Specifically, the inspectors observed the PPTs of the following instruments:
- Extender instruments; and
- RSO instruments.
b. Findings
No findings of significance were identified.
.3 Radiation Protection Technician Instrument Use
a. Inspection Scope
The inspectors observed RPTs performing in-field source checks of portable radiation survey instruments to verify that those source checks were adequately completed using appropriate radiation sources and station procedures. The inspectors assessed the RPTs use of radiation/contamination detection instruments as they provided radiological job coverage for risk significant work (e.g. the SI accumulator repair work in the Unit 2 Containment), as well as routine work, to ensure that the RPTs were utilizing the appropriate instruments. The inspectors monitored RPTs performing functional tests of selected contamination monitors, portal monitors, and small article monitors (i.e., for surveys of personnel and equipment prior to unconditional release from the RCA) to verify that they were source tested and calibrated as required by station procedures and industry standards.
b. Findings
No findings of significance were identified.
.4 Problem Identification and Resolution
a. Inspection Scope
The inspectors reviewed CY 2001-2002 CRs that addressed radiation monitoring instrument deficiencies to determine if any significant radiological incidents involving instrument deficiencies had occurred. The inspectors examined the results of a self-assessment (i.e., the Summary Report for performance Assurance Audit PA-0206, Radiation Protection) that focused on the licensees CR database and several individual CRs related to radiation monitoring instrumentation generated during the current assessment period. The inspectors also interviewed plant staff and examined closed CRs to verify that radiological instrumentation related issues were adequately addressed by the licensee. The inspectors evaluated these documents to verify the licensees ability to identify repetitive problems, contributing causes, extent of conditions, and the implementation of corrective actions to achieve lasting results.
b. Findings
No findings of significance were identified.
OTHER ACTIVITIES
4OA1 Performance Indicator Verification
