Reference:

Deckat No. 50-277/278 Peach Bottom Units 2 and 3 10CFR 20.403(b) i,6R. Report No.: 2-32-10/IP Occurrence Date: 4/13/82 Identificatien of Occurrence:

i Possible overexposure identified en Eberline TLD for =cnth of P. arch.

Conditions Pric: to Occurrence:

{

Unit 2 shutdown for refueling =aintenance cutage. Unit 3 operating at full power.

l Anparedt Cause of Occurrence:

Investigation into the badge exposure is in progress. The cause has not been identified. Preliminary investigation indictes that ta:pering l

with the TLD cay be involved.

Analysis of Occurrence:

The Eberline TLD badge which read a corrected exposure of 9.175 Res wa::

assigned to a laborer whose primary work assignment was in the laundry l

area. The individual was interview'ed and a work assignnent history identified. Raview of radiation work permits used by the individual

,oks indicated a total exposure of 0.250 Rc=.

Exposures read via tho

;;gt Barshaw TLD badge for the sazi time interval indicated an expcsura l gg of 0.240 Res. Other persennel wor. ling on the sa

e 7dPs alto had mg exposure d0sas within the ca:e icw' range.

IO 36 therline reported two abnor:alitias with the carticular TLD which read

~

$8 9.175 Res. The badge in cuestica was a Tchruary TLD, but V3S returned l 7 with the March batchof TLDs. In addition, the label on the particular 88 badge was upside down on the badge indicating that sc:e tas:pering ma.m may be involved.

1. • g if0

2-Based on the low exposure identified by the two other exposura monitoring mechanisms at Peach Sottom and an apparent tampering with the Eberline badge, it appears that an overexposure to this individual has not cccurrgd.

Corrective Action:

Following notification by Eberline, the individual's security badge was immediately removed.

This prevents the man frca entering the protective area and therefore all radicactive areas.

Work assignments have been provided to the individual cutsida the protected area while the investigation continues.

The man was also given a whole body count which showed less than 10% of the investigative limit and only naturally occurring radioactive isotopes.

The investigation will continue and a 30 day report will be issued.

This event was immediately reported to the site resident NRC inspector and via the Red telephone.

The delay in this written report occurred due to a misunderstanding of 10CFR 20.403(b).

It was believed that imediate verbal report was sufficient, and a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> written report was not required.

This misunderstanding hasbeencorrectedandthisreportQ3beingsubmitted.

Very truly yours, NAAW W. T. Ullrich Station Superintendent WTU:llh m.
