Q R
a.
The plant was in cold shu'.down tdr the entire month to perform repairs to the "A" and "B" High Pressure Injection Nozzles and the Auxiliary Feedwater H aders in both "Once Through Stea9 Generators"
.(0TSG). The status of the 4PI nozzle repair and the Auxiliary

With respect to the above two ite.
%C: Region V in a task interface agreement with NRR has been charged with the review of the licensee's QA/QC program, management controls and monitoring of the-licensee's repair activities. These activities-will be reviewed'during '

On May 10, 1982, the Region V office received a Part 21 report from the licensee concerning a Brand Rex defective electrical cable (Number 019411 manufactured under cable code K25). The
'
cable, a two conductor shielded #16 AWG cable, was found to be covered with white powder, and deteriorating possibly due to being subjected to adverse environmental conditions. The licensee has quarantined the cable reel and all other like reels and manufacturer
+
representatives have obtained samples in order to determine the cause of the deterioration.

U.S. Testing Company - P.evie'w of Quality Rec 6rds
.
Records of test,and'inspegtion;activ'ities performed by the site testing
laboratory, U.S. Testing, were reviewe'd. The records included water, cement and aggregate tests', concrete sampling and testing, and batch
~
plant inspection. The inspector;also verified that all measuring and test equipment was calibteted as required by Engineering and Inspection Instruction (EII) No. G-6 and 10 CFR 50, Appendix B Criterion XII.
All equipment was calibrated as: required, except for the following:
Inspection of the Gilson Shaker. and Screens revealed that the calibration
.
,,had expired on April 29, 1982, however, the records indicated that
<
' Aggregate. Sample No. AGD-20.I 'was tested using this equipment on May 12, 1982.
Sample No. AGD-20;l represented material that was used during concre'e placement no. 23. Placement No. 23 is a Quality Class I placement. Discussions with U.S. Testing personnel indicated that-they had utilized the equipment knowing that the calibration date had expired and without documenting the d_iscrepancy on a nonconformance
'
report.
In addition, EII NocG-6;in paragraph 2.1 states that, "The scope of this procedure covers those Rancho Seco measuring and test equipment and calibrated tools.which are maintained by Generation Engineering and required in support of construction requirements used

in activities affecting quality class. A master equipment list of these calibrated items shall be maintained by Generation Engineering Inspection Department." However, it appears that this procedure was never implemented, since a master equipment list for construction equipment did not exist.
The failure to follow quality procedures to assure that measuring and test equipment is properly controlled, calibrated and adjusted within specified limits is considered an apparent item of noncompliance with 10 CFR 50, Appendix B, Criterion V, " Instruction, Procedures, or Drawings."
