(Closed) Severity Level IV Violation 321, 366-85-12-02: Failure to provide adequate calibration procedures in the maintenance tool shop.
., The lic.ensee's response dated June 28, 1985, was considered acceptable by Region II.
The violation referenced major procedure deficiencies found in procedure HNP-6943, which has been replaced with 52CP-CAL-005-0S (Calibration Check on Precision Measuring Equipment - Revision 2).
The inspector reviewed 52CP-CAL-005-0S and both procedures in the ,, reference section of the procedure, 50AC-MNT-001-OS (Maintenance Program - Revision 5) and 51GM-TOL-001-0S (Maintenance Shop Measuring and Test Equipment Control - Revision 1). The current revisions of these procedures appeared to adequately implement the corrective actions for the referenced violation.
Additionally the inspector l reviewed the following procedures:

-l .. I 52CP-TOL-001-05, Torque Wrench Testing, Revision 1 ! 52CP-CAL-004-OS, Belt Tensioner Calibration, Revision 1 52CP-CAL-003-05, Crimping Tool Calibration, Revision 2 Although these procedures were not identified in the violation, the .j
- '
' licensee ' initiated or revised them during implementation of their corrective actions.
These procedures appeared adequate to perform their intended. functions.
The inspector reviewed evidence of training to the four procedures listed in this paragraph.
The licensee has satisfactorily addressed this item.
! ~f.
(Closed) Unresolved Item 321, 366/86-22-01: Electrical backseating-and light to light stroke time testing of motor operated valves, this item is covered by Violation 321, 366/86-30-02 and the licensee's corrective actions will be reviewed with the licensee's response'to the violation.

Unresolved Items l Unresolved items were not identified during this inspection.
l 5.
Licensee Action on Previously Identified Inspection Findings (92701) a.
(Closed) Inspector Follow-up Item 321,.366/86-22-04: ' Evaluation of additive torque wrench tolerance errors.
l ' The inspector reviewed General Maintenance Procedure 51GM-MNT-033-05 (Torquing Procedure - Revision 0) which. provides instructions for determining torque values, gasket stress, and stud stress.
This procedure adequately addresses the concerns of additive torque wrench tolerance errors, in that if a calibrated torque dial gauge cannot be added between the multiplier and the mechanical fastener, an engineering evaluation must be performed to ensure that no damage to equipment or fasteners will result from any errors introduced in the torque value by the torque multiplier.
b.
(Closed) Inspector Follow-up Item 321, 366/84-46-01: Establish an adequate program and controls to improve the present method of controlling vendor technical manuals.
The inspector reviewed Administrative Control Procedure 20AC-ADM-003-OS (Vendor Manual Control Revision 1), which - establishes the program to control the receipt, distribution, update and revision of plant vendor manuals.
The procedure established adequate control of the vendor manual program.
The inspector verified the implementation of the procedure by examining selected records and interviewing personnel in the document control area.
Additionally the inspector reviewed the documentation used by selected maintenance personnel. Although the program will not fully l l __
, .- l ! l$ ?,.Y ~ .
be implemented until July 1987, the inspector did not identify specific failures or programmatic. weaknesses.
The method for recalling checked out vendor manuals could be improved, in that l manuals were often checked out by clerks and delivered to engineers j, who were not aware of the requirement to return manuals in within 10 days. At the time of the inspection there were ten delinquent vendor i I manuals.
The licensee agreed to consider changes to the check out procedure. The overall program is considered acceptable.
c.
(Closed) Inspector Follow-up Item 321, 366-85-12-04: Program revision to ensure that evaluations of out-of-tolerance M&TE
addresses the issue of multiple scales and a uniform policy on previous usage is established.
The inspector follow-up item references General Maintenance Procedure 51GM-CAL-001-0 which has been replaced by 51GM-TOL-002-0S (Control of 1&C Measuring and Test Equipment - Revision 0).
Section 7.4 of 51GM-T0L-002-0S addresses the specific concerns of multiple scales in ! Section 7.4.2.
The inspection reviewed Section 7.4 of General Maintenance Procedure 51GM-TOL-001-0S (Maintenance Shop Measuring and l Test Equipment Control - Revision 1) and compared the requirements to l' those of 51GM-TOL-002-05.
The requirements for corrective actions when M&TE equipment is out of calibration is essentially identical.
There are no further concerns at this time, d.
(Closed) Inspector Follow-up Item 321, 366/85-12-03: Timeliness of out-of-tolerance evaluations to be procedurally and effectively controlled.
l The inspector reviewed General Maintenance Procedure 51GM-TOL-001-05, ) l' Revision 1, Section 7.4.
This section addresses test equipment found defective or out of calibration and gives specific instructions on actions to be taken. The guidelines are clear and the procedure , i appropriately addresses the concern.
Attachment 5, Calibration ) Certification Review Form, appears to provide adequate assurance that i l M&TE used during period of suspect calibration will be appropriately J ' evaluated.
e.
(Closed) Inspector Follow-up Item 321, 366/85-19-02: Procedure to Describe Preventive Maintenance Program.
The inspector reviewed Administrative Control Procedure 50AC-MNT-001-0S (Maintenance Program - Revision 5), which establishes the requirements and responsibilities for the control of maintenance ] l activities and adequately describes the preventive maintenance ' program.
The procedure clearly defines the different types of maintenance activities and gives clear guidelines for procedure development.

f.
(Closed) Inspector Follow-up Item 321, 366/85-19-01: Update Procedure to Reflect Maintenance Work Order (MWO) requirements.
The inspector reviewed Administrative Contrul Procedure 50AC-MNT-001-05 (Maintenance Program - Revision 5) which contained the current requirements for the MWO program.
The program and the implementing procedures appeared to edequately address the inspector's concerns. There are no further concerns at this time.
g.
(Closed) Inspector Follow-up Item 321, 366/86-31-01: Provide fire fighting training for encillary personnel.
The licensee intends to have ten Health Physics (HP) personnel trained per the requirements of OSHA section 1910.56.
Two HP personnel have received the training at the Georgia Fire Academy, one health physicist is currently in training.
The remaining seven are tentatively scheduled for training by the end of 1987.
h.
(0 pen) Inspector Follow-up Item 322, 361/86-22-05: Provide engineering review of causes of main streamline break detection -- instrumentation.
The licensee had submitted a request for engineering review to evaluate if the Fenwal switches need replacing, need improvements in calibration, or if the turbine building environment has an adverse effect on Fenwal switch performance.
The evaluation will also include a determination of the Reactor Protection System input requirements the of the switches.
The licensee expects to have the results of the evaluation completed by the end of 1987.
This item will remain open pending the results of the engineering evaluation and subsequent implementation schedule.
1.
(Closed) Inspection and Enforcement Bulletin 86-01 (321, 366/BU-86-01): Minimum Flow Logic Problems that could disable Residual Heat Removal (RHR) pump.
The inspector reviewed the licensee response to BU-86-01 and the associated drawings.
The subject of the Bulletin is not applicable to Plant Hatch in that there is divisional separation of the minimum flow bypass valves. A failure of the flow sensing instrumentation in one RHR loop will not affect the minimum flow bypass valves in the redundant loop.
