ATTACHMENT RESPONSE TO NOTICE OF VIOLATION 50-458/8616 LEVEL IV Reference Notice of Violation - J. E. Gagliardo to W. J. Cahill, Jr. dated May 1, 1986.

Request For Additional Information - J. E. Gagliardo letter to W. J.

Cahill, Jr. dated June 13, 1986.

A. FAILURE TO HAVE ADEOUATE PROCEDURES REASON FOR THE VIOLATION On March 25, 1986, in Memorandum No. PMG-M-86-62, the Plant Staff Maintenance Department removed torque wrenches from the controls of Administrative Procedure ADM-0029, " Control cf Measuring and Test Equipment (M&TE)", and provided new instructions for controlling torque wrenches. These program changes were made to provide controls for more reliable torque wrench calibrations by requiring the torque wrenches to have a calibration check before and after each use on plant equipment. The new program also expedited the process of issuing torque wrenches to Maintenance personnel. The M&TE device used to check the torque wrench calibrations remained under the control of ADM-0029. The new instructions also continued the use of M&TE Tracking Cards, as required by ADM-0029. Although the memorandum, issued on March 25, 1986, did establish controls for using torque wrenches at River Bend Station, the failure to implement an approved procedure in accordance with the requirements of ADM-0003 resulted in an apparent violation of Technical Specification Section 6.8.1.

CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED The new program, as described in Memorandum No. PMG-M-86-62, was discontinued on March 27, 1986 when the torque wrench calibration check. device was relocated from the resulted Maintenance Shop to the Site Standards Laboratory. This change from the device's calibration having been suspected as out of tolerance. When returned to the Standards Laboratory, the device's calibration was confirmed to be out of tolerance by a 1.4 percent error for readings above 225 ft-lbs when used in the counter clockwise direction. A review of the M&TE Tracking Cards for the torque wrenches used during the 3 days of the new program, revealed that the torque wrenches in question were not used in the counter clockwise direction or in the ranges found out of tolerance.

Therefore, all torque wrench applications during this period were acceptable.

As a result of the calibration check device being removed from service on March 27, 1986, subsequent torque wrenches issued were required to be performed in accordance with the controls of ADM-0029. To ensure compliance with ADM-0029, Memorandum No.

APM-M-86-59 was issued on April 2, 1986 rescinding the new program described in Memorandum No. PMG-M-86-62, dated March 25, 1986.

CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATIONS The responsible Plant Staff Maintenance personnel are aware of the requirements of ADM-0003. A review of memorandums issued by the Maintenance Department was performed. It was determined that memorandums are not used in lieu of approved procedures to provide technical guidance or control maintenance activities. Using memoranda in place of approved procedures is not standard practice at River Bend Stati'on. General Maintenance Procedure, GMP-0092 is presently being developed as an alternative to the torque wrench program described in ADM-0029. The procedure will meet the intent of the program described in Memorandum No. PMG-M-86-62 and establish approved instructions for the calibration and control of torque wrenches. The approval of GMP-0092 is presently pending-the receipt of a newly purchased torque wrench calibration check device. Torque wrenches will remain under the controls of approved procedure ADM-0029 until GMP-0092 is approved and issued.

DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED Full compliance with the requirements of ADM-0029 was achieved on March 27, 1986 after the relocation of the torque wrench calibration check device.
