Response to Inspection Report 83-12

Dear Sir:

Mr. J.R. White of your office conducted a routine safety inspection on April 26- ,

'29, 1983 at the Pilgrim Nuclear Power Station. Your letter dated May 18, 1983, reported the results of this inspection and identified two items of violation.

The responses to these two items of violation are provided below. Information regarding the representative sampling of the main stack and reactor building vent

.is provided under separate cover.

Item of Violation A (83-12-01)

Technical Specification 6.13, "High Radiation Area" requires that any individual or group of individuals permitted to enter areas greater than 100 millirem per hour be provided with or accompanied by one or more of the following:

1. A radiation monitoring device which continuously indicates the radiation dose rate in the area.

2. A radiation monitoring device which continuously integrates the radiation dose rate in the area and alarms when a preset integrated dose is received.

Entry into such areas with this monitoring device may be made after the dose rate level in the area has been established and personnel have been made knowledgeable of them.

-3. An individual qualified in radiation protection procedures who is equipped with a radiation dose rate monitoring device. This individual shall be responsible for providing positive control over the activities within the area and shall perform periodic radiation surveillance at the frequency specified by the unit Health Physicist in the- Radiation Work Permit.

Contrary to the above, from May 6,1981, to April 29,1983 (as a result of pro-cedures which failed to implement the requirements of this specification), indi-MNO G

! Mr. Thomas T. Martin, Director June 14, 1983 Page 2 i

i viduals were pemitted to enter areas between 100 and 10,000 millirem per hour in accordance with extended Radiation Work Permits without any of the provisions

identified in the stated requirement being implemented.

Response to Item A All extended radiation work permits for high radiation areas between 100 and 10,000 millirems per hour were reissued by April 30, 1983 to specify the required use of continuously indicating dose rate instruments for entry into these areas.

Supervisory personnel were verbally notified of this recuirement on May 2,1983.

All onsite station personnel were notified of this requirement and the provisions of Technical Specification 6.13 by a written memorandum which was issued on May j 4, 1983.

To prevent recurrence, Station Procedures 6.1-012, Access to High Radiation Areas, and 6.1-022, Radiation Work Permits, will be reviewed and revised as necessary to be consistent with the requirements of 10CFR20.203(c), as modified by Technical Specification 6.13. This action will be completed by August 1,1983.

i With the reissuance of extended radiation work permits by April 30, 1983, Boston i

Edison was in full compliance with the requirements of 10CFR20.203(c), as modified i by Technical Specification 6.13.

Item of Violation B (83-12-04) j 10CFR20.203, " Caution signs, labels, signals and controls," paragraph (d) requires 1

that any room, enclosure, or operation area in which airborne radioactive materials 4

exist in concentrations in excess of the amounts specified in Appendix B, Table I, Column I, be conspicuously posted with a sign or signs bearing the radiation caution symbol and the words, CAUTION - AIRBORNE RADI0 ACTIVITY AREA.

Contrary to the above, from April 18 to April 26, 1983, the following rooms were identified as containing airborne radioactivity in concentrations in excess of the amounts specified in Appendix B, Table I, Column I, and were not posted with

, the words, " CAUTION - AIRBORNE RADI0 ACTIVITY AREA":

Percent of Area Appendix B Values Clean Waste Pump Room 1032%

i Chemical / Waste Treatment Pump Room 212%

Response to Item B Upon discovery by the NRC inspector on April 26, 1983, the two rooms were ime-diately posted in accordance with 10CFR20.203(d). These rooms were subsequently sampled for airborne radioactivity on April 28, 1983 and were found to contain less than 25% of 10CFR20, Appendix B values.

• BOSTON EDISON COMPANY Mr. Thomas T. Martin, Director June 14, 1983 Page 3 To prevent recurrence, the health physics technicians at Pilgrim were reinstructed on the requirement to post airborne radioactivity areas in accordance with 10CFR 20.203(d). This reinstruction included both verbal and written instructions, and was completed on May 24, 1983.

Full compliance was achieved on April 26, 1983 when the rooms were immediately posted in accordance with 10CFR20.203(d).

Very truly yours,
