January 19, 1983 Mr. liarold R. Denton, Director Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Washington, D. C. 20555 Attention: Ms. E. G. Adensam, Chief Licensing Branch No. 4 Re: McGuire Nuclear Station Docket Nos. 50-369, 50-370 Outstanding Information Responses

Dear Mr. Denton:

In response to Ms. Elinor G. Adensam's (NRC/ DOL) letter of November 24, 1982, my December 22, 1982 letter transmitted several outstanding information responses needed for the NRC to complete its review of the Unit 2 operating license appli-cation as well as Unit 1 close out matters. Among the items transmitted were four Unit 2 relief requests, serial numbers MC-2-001 through 004 (reference Attachments 2A through 2D of my December 22, 1982 letter), for preservice examination.

Picase find attached a fifth Unit 2 relief request, serial number MC-2-005.

This problem was discovered towards the end of the inspection and it is anticipated that this will be the final relief request. This matter has been previously discussed with your staff in a telecon between Mr. P. B. Nardoci, et.al. (DPC) and Mr. R. Birkel, et.al. (NRC/NRR) on January 18, 1982. Should you have any questions with the attached information, please advise.

Very truly yours, J/a / 8 75cd/Ce6 Ital B. Tucker .

1. Component for which exemption is requested:

. Name and identi ficat ion Number:

Reactor Coolant Loop Piping Attachment Veld NC2FW 83-H47

b. Function:

Reactor '.colant Pressure Boundary

c. ASME Section 111 Code Class:

Class I

d. Valve Category: NA -

11. Reference Code Requirement that has been determined to be impractical:

! Table IW3-2600 i tem No. 84.9 reaui res volumetric ex' amination for integrally welded supports. Ultrasonic examination is impractical due to configuration, and radiography cannot be performed for inservice inspection due to accessibility.

See Attachment 1&2 l

111. Basis for Reques ti ng Relief:

l Estimate of preservice examination performed - 0%

l Original fabrication examination - dye penetrant l Measures which would be required to make the area accessible - Removal of Hanger 2MCR-NC-4203

S: rial No. MC-2-005 Page 2 of 2 111. Basis for Requesting Relief (cont.)

Removal of hanger would not give a meaningful volumetric examination.

Construction examination provided adequate assurance of component reliability.

IV. Alternate Examination: lione Available V. implemen tation Schedule: No inspection due to accessibility.
