Attachment to TXX-6402 May 7, 1987 Page 1 of 2 NOTICE OF VIOLATION ITEM B (445/8518-V-01)
A.
Criterion V of Appendix B to 10 CFR Part 50, as implemented by Section 5.0, Revision 3, dated July 31, 1984, of the TUGC0 QAP, requires that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings of a type appropriate to the circumstances and shall be accomplished in accordance with these instruction, procedures, or drawings.
Paragraph 4.4.5 of Gibbs and Hill (G&H) Electrical Erection Specification 2323-ES-100.
Revision 2, dated October 5,1980, requires electrical conduit installation to be in accordance with Drawings 2323-El-1701 and 2323-El-1702. Detail 18C of Drawing 2323-El-1701 limits the maximum length of conduit from an end device to its associated junction box to 15 feet.
Contrary to the above, the installed conduit lengths for primary coolant sample supply and return isolation solenoid valves 1HV-4631A and IHV-4631B were observed to be approximately 30 feet.
REVISED RESPONSE TO ITEM B 1.
REASON FOR VIOLATION Installation of electrical raceways for 1-HV-4631A & 1-HV-4631B is not in accordance with the requirements of the design. Construction procedures require engineering authorization in the form of design documents to be issued for any deviations from the design. However, the raceway was installed without a change to a design document.
QC Procedure QI-QP-11.3-28 did not adequately address the inspection requirements to detail 18C of Drawing 2323-El-1701 and 2323-El-1702.
2.
CORRECTIVE STEPS TAKEN AND RESULTS ACHIEVED a.
NCR E86-102718 was issued on June 23, 1986, to document unacceptable conduit installation for isolation solenoid valves 1HV-4631A and 1HV-4631B.
NCR E86-102718 was converted to NCR-CE-87-3226 on March 11, 1987 and was dispositioned by Engineering on April 23, 1987.
- 21,912, Rev. 2, was issued on April 29, 1987, to revise Detail 18 of drawing 2323-El-1701 allowing conduit runs of up to 50 ft. in length.
b.
CAR-063 was revised on July 29, 1986, to include walkdown and identification of Detail 18 installations.
Field verification has been performed in accordance with Engineering Procedure CPE-FVM-EE-022, " Instruction to Acquire Data for Tracability of IE Pigtail Extensions".
Detail 18 walkdowns for Unit 1 and Common are complete with 31 Class IE detail 18C splices and 40 Class 1E detail 18C pigtails identified. An engineering evaluation of these installations is in progress.
In the event an installation exceeds the 50 ft.
maximum it will be documented on an NCR. Resolution of CAR-063 includes the above corrective action associated with NCR-CE-87-3226.
A similar program is being developed for Unit 2.
Attachment to TXX-6402 May 7, 1987 Page 2 of 2 REVISED RESPONSE TO ITEM B - CONT'D 3.
CORRECTIVE STEPS TO AVOID RECURRENCE a.
Applicable craft personnel were retrained in the existing procedures l
to be followed in requesting deviations from the design documents.
b.
QC Procedures QI-QP 11.3-28 was revised on March 7, 1986, to include specific inspection requirements to Detail 18C of drawing 2323-El-1701 and 2323-El-1702, and revision training for appropriate QC Inspectors has been performed.
4.
DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED Full compliance will be achieved with the completion of CAR-063 scheduled for August 31, 1987 - Unit 1 and Common, and March 31, 1988 - Unit 2.
