ATTACHMENT RESPONSE TO NOTICE OF VIOLATION 50-458/8711-01 LEVEL V I

REFERENCE Notice of Violation - J. E. Gagliardo le'ter to J. C. Deddens, dated May

^

t 29, 1987. -

FAILURE TO USE ODCM METHODOLOGY TO PROTECT DOSES s Technical Specification 3/4.11.1.3 states that doses due to liquid l releases to unrestricted areas shall be projected in accordance with the )

methodology and parameters in the ODCM. This requirement is implemented by the use of Surveillance Test Procedure (STP)-511-8208. {

Contrary to the above, the NRC inspector determined on April 15, 1987, that the calculations performed using the format in STP-511-8208 during the period July 1986 through March 1987, did not agree with the methodologies specified in the ODCM.

This is a Severity Level V violation.

REASON FOR THE VIOLATION:

Personnel error was determined to be the reason for this oversight. A change to STP-511-8208 was drafted in conjunction with the ODCM revision but not issued for revision and approval. Personnel in Radiological Engineering did not follow up on the change to ensure it was incorporated.

CORRECTIVE STEPS WHICH HAVE BEE 7 TAKEN AND THE RESULTS ACHIEVED:

Temporary Change Notice (TCN) Number 87-0343 was submitted on 4/16/87 and approved on 4/21/87 to correct STP-511-8208 to agree with the ODCM methodology.

Comparisons of the two calculational methods were performed for the period since the ODCM method was changed. Using the less conservative STP methodology, entrance into the Technical Specification 3/4.11,1.3 action statement was required in July and October 1986. Using the ODCM methodology, two additional months - November 1986 and January 1987, required entrance into the action statement. A review of radioactive releases during these months indicated that all releases were treated via the radioactive waste treatment system prior to their discharge as required under Technical Specification 3/4.11.1.3.

CORRECTIVE STEPS WHICH HAVE BEEN TAKEN TO AVOID TURTHER VIOLATIC,NS The ODCM/ Procedure revision log (Attachment I to RSP-008) will be revised to incorporate a sign-off by the Radiological Engineering Supervisor or his designee to review, for applicability, any change (s) to lower tier implementing procedures with regard to ODCM revisions. This should assure revisions and changes are implemented as appropriate.

DATE VHEN FULL COMPLIANCE WILL BE ACHIEVED STP-511-8208 has been revised (TCN 87-0343) and approved on 4/21/87.

The RBS dose projection procedures are in compliance with the current ODCM methodology.

The ODCM/ Procedure revision log vill be revised by August 14, 1987, l
