ATTACHKENT 1 l

Supplemental Response to Violation 8906-01, Example 1 k Although LP&L believes that the torquing program at Waterford 3 is adequate, there is potential for improvement to preclude the recurrence of noncompliance related to torque requirements. After receiving Violation 8906-01 (Example 1), actions to prevent recurrence were initiated, but a discussion of these actions was not provided in LP&L's response to the violation. First, a review by maintenance planners of repetitive tasks, e.g., alignment checks, was initiated to ensure that specific torque values from the Vendor Manuals are included in applicable work packages. This ongoing project is being handled on a case-by-case basis as the tasks bacome due. In addition, departmental meetings were used to heighten personnel awareness of the 8906-01 torquing issu Additional actions will be taken to emphasize management's desire to have an effective, comprehensive torquing progra To elevate the awareness of the torquing noncompliance and bring such ,.

conditions to the attention of the proper personnel lessons learned training will be given to maintenance personnel, including the first line supervisory level, Also, during periodic maintenance " shop" and first line supervisors' meetings, the issue of torquing compliance will be re-emphasized and f eedback on torquing concerns will be solicite t l

The upper tier torquing procedure, MM-6-011. " General Torquing and Detensioning," will be revised and human factor engineered to increase user l awareness and understandability and to reduce the chances for personnel erro Upon completion of the rewrite, training on the procedure will be conducted with cognizant maintenance personne Finally, a review of applicable maintenance procedures will be initiated to I alleviate any inconsistencies or hard spots in the area of fastener torquin Based on the above actions, which are scheduled for completion by December 29, 1989, LP&L is confident that recurring noncompliance in the control of safety-related fastener torque requirements will be prevented in the futur As stated in your letter, LP&L's original response to Violation 8906-01, Example 1, neglected to address the failure to torque the coupling bolts in accordance with the vendor Manual requirements. Failure to reply to this ;

part of the violation resulted from confusion in having to address two separate torquing issues that occurred during the performance of Work Authorization 01028798 and the use of Vendor Instruction Manual 457000254. The following information is being provided to supplement LP&L's original response to Violation 8906-01, Example _ _ - _ - _ - _ _ _ _ _ _ - _ _ _ _ _ _ _ . _ _ _ _ _

The. alignment check that was performed on ACCW Pump IB under Work Authorization 01028798 took place at approximately 2:00 a.m. on 2/8/89. At the point in which the coupling bolts had to be tightened, the responsible mechanics went to the applicable Vendor Instruction Manual (No. 457000254,

"B&W Pumps") to obtain the instructions for coupling assembly. When the mechanics determined that additional instructions for Koppers fast couplings were needed but not included in the Manual, they contacted their supervisor at home to request his assistance. The supervisor, based on his J knowledge of Koppers couplings, informed the mechanics that no torquing was required and instructed them to install the coupling using toolbox knowledge. Subsequently, it was learned that a later revision to the Koppers fast coupling instruction sheet did in fact contain requirements for torquing the coupling bolts. A Quality Notice (QN QA-89-078) was then generated on 3/3/89 to initiate corrective action for this condition. In response to the QN, it was determined that the lack of precise torquing of the coupling bolts had no detrimental effect on the operation of the coupling. The purpose for bolt torquing is strictly to avoid overstressing the bolt as was confirmed by the vendo .

Koppers Installation and Alignment Instuction Sheet 1900-01, which includes l the torquing requirement (Note: The earlier revision, Sheet 1900, did not I include the torquing requirement), has since been incorporated into Vendor'~ j Instruction Manual 457000254 Incorporation of this document into other j applicable Manuals is in progres l
