u, ATTACHMENT I Violation:

10 CFR 20.201(b) requires that each licensee make such surveys as may be necessary to comply with all sections of Part 20. As defined in 10 CFR 20.201(a), "survey" means an evaluation of the radiation hazards incident to the production, use, release, disposal, or presence of radioactive materials or other sources of radiation under a specific set of conditions.

Contrary to the above, during the period of February and March 1988, several workers entered the drywell torus room and worked in areas in which the radiation fields had not been properly surveyed to ensure compliance with 10 CFR 20.201 and 10 CFR 20.202.

The dose rates in the work area were later found to be higher than expected.

This resulted ir radiation exposures to unmonitored areas of the workers bodies that were higher than expected.

Response

GPUN concurs with the finding stated in the Notice of Violation and wishes to again point out that this item was identified during our own investigation.

This investigation was precipitated by the discovery, during our daily assessment of SRD exposure readings, that worker exposures were higher than expected.

Listed below is the reason for the violation, the completed and planned corrective steps and the date when full compliance will be achieved.

Reason for the Violation:

The Radiological Controls Technician on the job improperly assessed the radiation fields as being fairly unifom to all major portions of the whole body in the work area, and thereby concluded it was only necessary to document general area radiation levels. However, radiation levels were, in fact, nonuniform and were discovered to be significantly higher to the head and thigh regions of individuals in some portions of the work area than expected based on general area radiation levels.

Corrective Steps Taken and Results Achieved:

Upon discovering nonuniform radiation fields, work was stopped and an exposure assessment was performed for all individuals who had worked in the area. Worker exposure records were adjusted accordingly.

No administrative overexposures had occurred. Requirements for dosimetry on the head and thigh regions of individuals, and for notification of Radiological Controls Supervision and Engineering in the event periodic surveys reveal changes in dose stratification, have been established for subsequent work. This resulted in proper monitoring of radiation exposures to workers in the area.

The individual who performed the survey (a contractor) is no longer employed at Oyster Creek.

Corrective Steps to Avoid Further Violation:

The Radiation Controls Department is performing a root cause evaluation iniarder.to establish appropriate long term corrective actions.

The evaluation and corrective action-implementation schedule will be completed by June 30, 1988, Date of Full. Compliance:

Measures to achieve full compliance for the specific task, drywell torus room cathodic protection were completed on April 19, 1988.

Programmatic efforts designed to prevent similar items of noncompliance in the future will be scheduled by June 30, 1988.

These efforts will be completed prior to August 30, 1988 and will be available for NRC review, i
