Subject:
Docket 70-734: Notice of Violation Required Response.
Ref. (a): NRC ltr, Docket 70-734 dtd 3/12/82.
Dear Mr. Engelken:
This is in response to your letter, reference (a), which includes a notice of violation relating to the requirements of 10 CFR 70.24(a). This notice follows an inspection by your staff which in part reviewed a situation which was reported to your office on February 5, 1982. Our report included the ac-tions taken to remedy the deficiency.
Appendix A of your letter requires that this response contain a written statement or explanation in reply, including (1) the corrective steps which have been taken and the results achieved; (2) corrective steps which will be taken to avoid further items of noncompliance; and (3) the date when full compliance was or will be achieved.
General Atomic is involved in a major modification to its Sorrento Valley fuel manufacturing facility to comply with the Commission's 10 CFR 73 upgrade physical protection rule. The facility's fuel production had stopped on or about August 31, 1981, and process materials were placed in vaults. Criti-cality alarms in vaults were operative at all times. The only activities involving the handling of SNM were operation of the non-destructive assay equipment, QC Lab and the packaging and measurement of radioactive waste gen-erated in the facility modification.
To make way for the rrmoval or relocation of equipment and installation of new wiring conduit neci7sary as part of the facility modification, certain system components were +'is; onnected.
Inadvertently a few criticality moni-tors were disabled. On February 5,1982, the situation was discovered.
Immediately reinstallation of the required criticality monitors began.
Concurrently we reportcd the situation to your office. Reinstallation and monitor checkout continued until the task was completed. Full compliance was achieved on February 6, 1982, when all required criticality alarms were restored to active service.

R. H. Engelken 696-3069 We believe recurrence of this type of violation can be prevented by rewriting our HPD-4, " Criticality Warning Alarm Instrument & System Maintenance & De-activation Procedure," to require written notice to and approval of the Manager, Health Physics, and Facility Management for temporary deactivation of a criticality detector or written notice to and apporval of the Manager, Health Physics, Facility Management, and the Criticality and Radiation Safe-guards Committee Chairman prior to permanent deactivation of any criticality warning detector or system.
A copy of this revised procedure is attached for your information.
We remain hopeful that our corrective actions and this response are adequate.
Should you have additional questions, please don't hesitate to contact me.
Very truly yours, 4 h William R. Mowry Licensing Administrator Nuclear Materials Control Division WRM:he
