[

'Arkanias Nuclear One', Units 1.& 2.

Licenses: DPR-51 NPF-6 During an NRC inspection conducted October 1 through November 15, 1989, three violations of NRC requirements were identified.

The violations involved failure to properly torque-fasteners on plant equipment, failure to meet the.

Technical Specification-(TS) requirements for the required number of operable'

-log channel power monitors, and failure to maintain appropriate plant procedures.

In accordance with the " General Statement of Policy-and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1989)-(Enforcement

Policy), the violations are listed below

A._

Failure to Properly Torque Fasteners

' Unit 2 Technical Specification 6.8.1 requires that written procedures be

-established, implemented, and maintained' covering the activities recommended =in Appendix A of Regulatory ' Guide 1.33, Revision 2, February 1978.

Appendix A,. Item 8, includes' procedures for control of measuring and test equipment and for surveillances tests, procedures, and calibration.

Plant Procedure 1025.020, " Bolting and Torquing Guidelines,"

has been established in accordance with this Technical Specification

' requirement.

Paragraph 8.4 2.A,3 of Plant Procedure 10251020 requires the indicated torque be corrected in accordance with Attachment 4 when using a universal joint that extends the point of applied to_rque.

Contrary to the above"on;0ctober-2, 1989, the inspector observed the use of a universal joint when torquing fasteners on the, fuel injector collar plates for-Emergency Diesel Generator-2K-4B.without the indicated torque being corrected.

This is a Severity Level IV violation'.

(Supplsment I)'(368/8940-01)

B.

Failure to Meet TS Requirements Unit 2 Technical' Specification 3.3.1, for reactor protective

' instrumentation states, "As a minimum, the reactor protective

instrumentation channels and bypasses of Table 3.3.1 shall be Operable...."

Table 3.3.1 states that for Modes 3, 4, and 5, at least two i

. logarithmic (LOG) power level channels shall be operable.

Contrary to the above,fonl0ctober 4 'and 5,1989, less than two log power levelschannels were operable ~in that all.four channels had been removed from service for maintenance du. ring a-refueling outage.

This is a Severity Level IV' violation'.

L C.7 Failure to Maintain Appropriate Plant Procedures 2

~

Unit-2 Technical Specifisation 6.8.1 requires that written procedures be established, implemented, and maintained covering the activities recommended ~in Appendix; A of? Regulatory Guide 1.33,. Revision 2, February 1978.. Appendix A, Item 8, includes procedures for control of measuring and. test equipment-and for surveillance tests, procedures, and calibrations'. -In addition,' Appendix A,: Item 9, includes procedures for

. performing' maintenance.

Plant Procedure 2306.005, "18 Month Surveillances on Unit 2 Emergency Diesel Generator 2K-4," and 2406.096, "2BS-1A/B Disassembly, Inspection.and' Reassembly," and Plant Procedure 1025.020,.

'" Bolting and Torquing Guidelines," have been' established in-accordance

. ith.this TechnicaliSpecification requirement.

w p

' Contrary to.the above, written procedures applicable to TS 6.8.1 were not appropriately-maintained as described in the four examples discussed below:

'I.

Stepf8.3.10 of Plant Procedure 2306.005 requires torquing of-

' fasteners lto 37 ft.lbs. for the reinstallation of the emergency diesel generator (EDG) fuel injector nozzles. The Fairbanks Morse

? technical manual for the EDG specifies a torque valve of 20-25 ft.lbs. for these fasteners.

2.

Step 8.3.1 of Plant Procedure 2306.005 requires a test pressure of 30-50 psiglfor'the hydrostatic pressure' test'of the EDG engine jacket water system. The Fairbanks Morse technical' manual for the EDG specifies a hydrostatic pressure of 50 psig for this test.

' 3.-

Steps 8.3.12 and 8.3.17 of Plant Procedure 2402.096 requires torquing of the--bearing cover fasteners to 160. f t.lbs. and cover plate F

fasteners to-243 ft.lbs, for Valves 2BS-1A/1B (refueling water tank-discharge check valves). The Atwood and Morrill technical manual that was used to obtain'this-information is not' applicable to

-Valves 2BS-1A and'1B. The. correct torque values for the bearing a

cover fasteners is 35 ft.lbs. and 305 ft.lbs. for the cover plate j

fasteners as noted in the= vendor manual for this type of valve.

4.

Step 8.4.2.A.3 of Plant Procedure 1025.020 requires that the indicated v

torque be corrected in accordance with Attachment 4 when using a

, universal joint that extends the point of applied torque. However, does not provide instructions for correcting the applied torque for universal joints.

In the' aggregate, these examples constitute a Severity Level IV violation.
