. I Attachment 1 NG-87-1015 Response to IR 86-19 NRC Item of Violation (Severity Level IV) 10 CFR 50, Appendix B, Criterion V, as implemented by Duane Arnold UFSAR, Section 17.2.5, requires that activities affecting quality be prescribed by documented instructions and procedures and accomplished in accordance with those instructions and procedures.

Contrary to the above, the licensee failed to perform use history evalua-tions for measuring and test equipment found out of calibration as required by Procedure No. MD-017 Resoonse to Item of Violation

1. Corrective Action Taken and the Results Achieved DAEC had issued Procedure No. MD-017, Performance Of Use Histories On Out of Calibration Measuring and Test Equipment (M&TE), Revision 0 on July 3, 1985, and Revision 1 on September 3, 1986. The inspector determined from interviews with mechanical shop personnel responsible for control of M&TE that they were not aware of Procedure No. MD-017. M&TE which had been found out of calibration and had not been evaluated per MD-017 were:

- Outside micrometer No. Q-29, found out of calibration on September 13, 1986.

- Torque wrench No. Q-248, found out of calibration on November 19, 1986.

- Depth micrometer No. Q-14, found out of calibration on February 2, 1986.

- Torque wrench No. Q-256, found out of calibration on October 10, 1986.

Use histories on this equipment were evaluated by February 4, 1987. This evaluation revealed that only two of the above items of measuring and test equipment had been used since their last successful calibration. These items were torque wrench No. Q-256 and depth micrometer No. Q-14. The evaluations concluded that the use of these two items did not result in any equipment operability concerns.

One previous use of the depth micrometer was for information gathering only and no maintenance was performed as a result of the information. The other use was to verify minimum thrust clearance for a bearing. The clearance measured by the depth micrometer was well beyond the minimum and the amount by which the micrometer was out of calibration was not great enough to reduce this clearance below the minimum.

Attachment 1 NG-87-1015 Page 2 Two maintenance activities had been performed with the torque wrench which required calibrated torque values. In one ~ase,c a pipe flange was torqued and has since been removed. In the other case, a pump coupling was torqued. In neither case was insufficient torque applied because the wrench was unaffected in the clockwise (tighten) direction. The torque wrench was out-of-calibration only in the counterclockwise direction by a maximum of approximately 4%.

Maintenance Procedure MD-017 has been revised to require that Maintenance Engineering, rather than the Maintenance Foreman as was previously re-quired, be notified of measuring and test equipment found to be out-of-calibration. The procedure also now requires that Maintenance Engineering perform use history evaluations within 14 days of being in-formed that equipment is out-of-calibration. Any necessary corrective actions identified by this evaluation will be performed as soon as practi-cal. All maintenance personnel had received training on Procedure MD-017 previous to the inspection. Training on the latest procedure change has also been performed.

2. Date When Full Compliance will be Achieved Full compliance was achieved on February 4, 1987, when use history evalua-tions were performed on the out-of-calibration equipment. The revision to the use history evaluation procedure will prevent future occurrences.

NRC Item of Violation (Severity Level VI 10 CFR 50, Appendix B, Criterion VI, as implemented by the Duane Arnold UFSAR, Section 17.2.6.1, requires that documents, including changes, are reviewed for adequacy, are approved for release by authorized personnel, are distributed to and used at the locations where the prescribed activi-ties are performed, and are controlled.

Contrary to the above, the licensee had not maintained a completed and up-to-date set of Piping and Instrumentation Diagrams (P&ID's) in the control room for use by the reactor operations personnel.

Attachment 1 NG-87-1015 Page 3 Resoonse to Item of Violation

1. Corrective Actions Taken and the Results Achieved The inspector reviewed the status of Document Control and determined that the master indices for drawings, manuals, Technical Specifications, UFSARS, instructions and procedures were generally maintained in an acceptable manner. The required revisions of documents were distributed and used at the work locations with one exception. The set of P& ids had been main-tained in the control room for use by the operations staff was incomplete.

Revisions to three P& ids were missing. The affected drawings were No.

M-115, No. M-116, and No. M-184. The three P& ids were missing for an indeterminate period of time. In each case, a copy of the corre-sponding Advanced Information Drawing (AID) was available in the control room. The AID included various proposed, in process, completed, and veri-fled as-built changes, so the control room operator had some alternate information available.

All controlled permanent drawings require transmittal acknowledgements of receipt of the drawings to Design Engineering. Such acknowledgments for the missing revisions had been received by Design Engineering. It appears, therefore, that the drawings were removed by unknown personnel after they were received. Design Engineering replaced two of the missing drawings after receiving notification that the drawings were absent on the week of January 19, 1987. These drawings were temporary black-line drawings.

M-184 was not replaced untti March 3, 1987 because it was originally iden-tified as M-117. M-117 was current. All control room personnel were also notified in writing of the missing drawings and reminded of their responsi-bility to maintain the drawing files intact. As an additional corrective action, Design Engineering is now performing monthly inventories of control room P& ids. A complete inventory of all control room drawings (approxi-mately 2300) is currently being performed and will be complete by March 31, 1987.

2. Date When Full Comp 1tance will be Achieved Full compilance was achieved on March 3, 1987, when all missing drawings were replaced in the control room.
