Dear Mr. Spessard:
INSPECTION REPORT NO. 50-483/82-13 This reply is in response to your letter of October 27, 1982 which transmitted the report of the inspection conducted at Callaway Plant, Unit 1 during the period of September 1 to 30, 1982.
Our responses to the items of noncompliance are presented below in the ord' - listed within the body of inspection report number 50-483/82-13.
The due date for the response was extended to December 17, 1982 by Mr.
J.
E.
Konklin.
None of the material in the inspection report or in this response is. considered proprietary by Union Electric Company.
(50-483/82-13-01)
SEVERITY LEVEL V VIOLATION 10 CPR 50, Appendix B, Criterion XIII, states, " Measures shall be established to control the handling...and preservation of material and equipment...to prevent damage or deterioration."
SNUPPS Standard Quality Assurance Manual, Section 6.2.6.2 states, "Each utility's QA organization shall audit the measures applied at their site...to verify that controls for installed materials are adequate."
Contrary to the above, the inspector found that control measures for installed equipment protection were inadequate to prevent damaging the jacket and insulation on cable 4EJG04BF and exceeding the minimum bend radius on other cables entering cable tray section 4U2A39 from conduits 4U2AlL and 4U2AlZ.
Response
Corrective Action Taken And The Results Achieved:
Deficiency Report 2SD-8334-E was written to document the minimum bend radius violation and damage to cables in conduits 4U2AlL and 4U2AlZ.
Cables 4EJS10BA, 4EJG06BH and 4EJG04BF were removed and DECQQj882 B301110152 830105 PDR ADOCK 05000483 O
Mr,.
R.
L.-.Spescard Dectmber 17, 1982 new cables were repulled.
Conduits 4U2AlL and 4U2A1Z were reworked so that the conduits do not extend above the siderail of tray 4U2A39.
Other miscellaneous items were removed from cable-trays 4U2A39 and 4U2A38; no other cables were found to be damaged.
Additionally there has been a 100 percent walkdown/ inspection of all safety-related exposed cable performed by Quality Inspection-Electrical.
The results of this walkdown/ inspection have identified similar deficiencies which are being handled in accordance with established project requirements.
The Project Electrical Manager has issued a project memorandum to all Delcon personnel to address cable concerns.
The Safety Manager has included information on protection of electrical cable in the Weekly Tool Box Safety Meetings for all craft personnel.
Training for electrical craftsmen in cable pulling and terminating has been accomplished for minimum bend radius violations and other cable pulling and terminating concerns.
This training was
?
completed November 9, 1982.
Corrective Action To Be Taken To Avoid Further Noncompliance:
The minimum bend radius violation identified in.the inspection report resulted from a problem of not adequately controlling construction activities in the area.
Protection of electrical cable has become a monthly topic for discussion in the Weekly Tool Box Safety Meetings for all craftsman.
In addition, Union Electric Nuclear Engineering and Bechtel are reviewing the case of a cable exiting a vertical conduit and then entering a horizontal tray to determine if there is a problem with the generic cable tray / conduit interface design.
Bechtel believes that the design is adequate.
However, if it develops that a change is necessary, we will update our response by December 31, 1982.
The Date When Full Compliance Will Be Achieved:
Training was completed on November 9, 1982 to achieve full compliance.
(50-483/82-13-03) SEVERITY LEVEL V VIOLATION 4
10 CFR 50, Appendix B, Criterion V, states, " Activities affecting quality shall be prescribed by documented instructions, procedures or drawings...and shall be accomplished in accordance with these instructions, procedures and drawings."
i Daniel International Procedure WP-03, states in Section 3.7, "After a Seismic II/I, and Group "D" support is erected, the location and configuration shall be verified and documented for conformance to design drawings..."

Mr,.
R. L.
Spessard December 17, 1982 Contrary to the above, the inspector found the piping support for the floor drain line above Essential Service Water Valve EF-HV-37 power supply cables was not installed nor was conformance to design verified and documented according to procedure.
Response
Corrective Action Taken And The Results Achieved:
Through discussion with Bechtel it was determined that they had previously identified the subject Seismic II/I deficiency.
Bechtel is currently designing shielding for the subject condition which will bring it into compliance with Seismic II/I requirements.
Subsequent to the NRC inspection an additional II/I deficiency was identified.
However, it was determined that this case had also been identified as a II/I deficiency by Bechtel and was listed on an action plan of the Hazard Protection Task Force.
Corrective Action To Be Taken To Avoid Further Noncompliance:
Ongoing efforts of Bechtel's Hazard Protection Task Force will provide assurance that the design meets II/I requirements.
The Date When Full Compliance Will Be Achieved:
Bechtel will transmit the design change to correct the floor drain line deficiency identified by the NRC inspector by January 3, 1983 and corrective action will be completed as the construction schedule permits.
If you have any questions regarding this response or if additional information is required, please let me know.
Very truly yours, Donald F.
