Dear Mr. Martin:
Your letter of November 6, 1984, forwarded Combined Inspection Nos. 50-277/84-25 and 50-278/84-21 which. cited certain activities at'our Peach Bottom Atomic Power Station which did not seem to be in full' compliance with NRC requirements.
These apparent violations are restated below followed by our responses.
Finding A.
Appendix "A"
to License Nos. DPR-44.and DPR-56, Technical Specifications Section 6.11, requires that procedures for personnel radiation protection shall be approved, maintained and adhered to for all operations.
(1)
Procedure HPO/CO-32,-" Quality Control of Personnel Dosimetry", requires that a correction factor be calculated for:Harshaw dosimetry and used to correct the bias of the Harshaw dosimeter results.-
(2) Procedure HPO/CO-13E,
" Accounting for Lost Badges", requires that there be an evaluation and trending of the loss of dosimetry for major work groups.
Contrary to the above, as of August 23, 1984, (1) correction factors have not been calculated and used to correct the bias of Harshaw dosimeter results and (2) there has been no evaluation or trending of the loss of dosimeters for major work groups.
This is a Severity Level V violation.

" Response A.11 Correction of Harshaw readings had been performed in the past, however, due to personnel. error resulting from a change in personnel in.the dosimetry office, the process had been stopped.
The Harshaw readings are not.used for official records but rather for
. administrative control and exposure estimation.
Since they histcrically have provided high. reading, and were therefore on the conservative side, due
-diligence was not given to the procedural requirements.
Health Ph'ysics-personnel have now been directed.to comply with HPO/CO-32, " Quality Control of Personnel
. dosimetry", and apply correction factors to Harshaw TLD results.
A conservative correction factor'of 1.0 will be substituted when correction factors are calculated to be'less than one.
A correction factor of less than one will not be used without the approval of the Senior Health Physicist.
These actions should prevent future recurrence of'this violation.
A.2 This failure resulted from. administrative oversight following a personnel' change in the dosimetry office.
Prior to this change, records of lost dosimetry were tabulated and utilized to produce a Lost' Badge Summary. Report which is included in the Health Physics and Chemistry' Management ~ Report submitted to' the Plant Operations Review Committee (PORC) and retained as a record in the PORC minutes.
Upon notification of this shortcoming, trending of lost. dosimetry was reestablished and lost dosimetry reports were generated for every month'since July 1984.
No unusual or adverse trends were identified for any one work group or individual in these reports.
As additional corrective measures, which should serve to prevent recurrence of this failure, 1) a routine test will be generated and. scheduled to ensure that dosimetry losses are evaluated and 2) HPO/CO-13E, Accounting for Lost Badges, will be revised to clarify this evaluation program.
These corrective actions will be completed by February 1, 1985.
