ILLINOIS 61727 January 29, 1985 Docket No. 50-461 Director of Nuclear Reactor Regulation Attention: Mr. A. Schwencer, Chief Licensing Branch No. 2 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D.C. 20555

Subject:

November 20, 1984 Resolution Meeting on ASME Section III Subsection NF Boundary Jurisdiction

Dear Mr. Schwencer:

On November 20, 1984 Illinois Power (IP) held a meeting with Mr.

Horace K. Shaw of Nuclear Reactor Regulation Mechanical Engineering Branch and Mr. Frank J. Jablonski of Region III to resolve the NRC IE Inspection Report Number 50-461/83-09, dated August 15, 1983 concerns regarding the code boundary jurisdiction between ASME Section III, Subsection NF, 1974 Edition, Summer 1974 Addenda and American Institute of Steel Construction (AISC) Standards. Attached for your information are meeting minutes and a copy of the IP presentation.

It is our understanding as a result of this meeting that NRR and Region III accept IPs application of the boundary jurisdiction of these codes on the Clinton Power Station.

Sincerely yours

/

.1. Purpose

- The purpose of the meeting was to resolve the Notice of Violation dated August- 15, 1983, Inspection Report Number 50-461/83-09, by:

a. Presenting to the NRC/NRR the basis used to define the NF 4 ' boundary jurisdiction for Clinton Power Station (CPS) ASME component supports,

b. Demonst' rating that the Codes and Procedures applied to CPS

. auxiliary steel are compatible with the requirements of the NF code.

Copies of all' exhibits discussed during the meeting are attached-to

.these notes as Appendix A.

Background (cont'd)

This response was not accepted by the NRC Region III and was  ;

referred to the Office of Nuclear Reactor Regulation for resolution

as noted in the following letter:

NRC's letter from Mr. R. C. Knop to Mr. W. C. Cerstner dated October 28, 1983. 1

3. NF Boundary Jurisdiction

, CPS has defined ASME component support members which are in direct contact with the pressure retaining boundaries as NF. The structural steel shape members which connect the component support to the building structure were defined to be Auxiliary steel. This Auxiliary steel was designed to the rules of.the AISC Code.

Examples are shown in Exhibits 1 and 2. Members A and B in Exhibit

. t 1.are classified as NF, but Members A and B in Exhibit 2 are classified as auxiliary steel. These definitions of the boundary jurisdiction are the same or.are similar to many other stations of the same code of-record.-

4. Basis for Clinton Classification The rationale.for the classification explained-in Item 3 above is as follows: ,

a. . Paragraphs NCA-3220 (J) and NCA-3252 of ASME Section III and

. Paragraph III-1-79-94 of the Section_III-Code Interpretation

. Book Number 5 indicate that.it is the re'sponsibility of the owner'to determine the' jurisdictional boundaries.

A 7

b.. .The applicable ASME Code for Clinton is.the 1974 with the

-Summer. Addenda which did not include stamping requirements for

- component supports. The AISC requirements for these structural shapes were essentially the same as.NF.

t

. Comparison of AISC and NF Requirements

~

5.

LWe.have compared the requirements of AISC vs. NF for design, materials, and examination and inspection..and our conclusions follow:

'a. Design All non-NF auxiliary steel'is designed in accordance with -l AISC. -The'NF. Design requirements for auxiliary; steel were

based upon the AISC-requirements. .The differences in design i 1 requirements have been identified and the major' items of the survey are

.)

Notes of Meeting -

November 20, 1984 Page 3

5. . Comparison of AISC and NF Requirements (cont'd)

a. Design (cont'd)

1. Effect of temperature on allowable stress for NF

2. Stability limit is lower than AlSC

3. The allowable stress for SSE loads is lower than AISC

4. Weld' allowable stress is lower The above differences are small and were determined to have no effect on the CPS design.

b. Materials The material for all non-NF auxiliary steel is in accordance with the AISC/AWS Codes. The component supports for CPS are not required to be NF' stamped. The materials used for CPS are compatible with NF Code.

S&L specifications require certified material test reports (CMIR) for. auxiliary steel and welding materials. These CMIR's are compatible with the NF requirements and are maintained'on record at the CPS.

Certificates of Compliance for bolting materials are adequate and are available at the site.

Materials were controlled, similar to ASME Code requirements,

-to assure.that only correct and accepted material was used per the applicable drawing requirements.

Welding of auxiliary. steel: components was_ performed using Jwelding procedures and welders qualified.to the requirements

~of AWS D1.1 or ASME,Section IX. Welding materials were controlled in accordance with ASME Code requirements, using acceptable procedures. Also, adequate provisions exist for repairing unacceptable material defects.

c. . Examination'and Inspection

.All non-NF classified _ welds have been 100% visually' examined in accordance with'the AWS D1.1 criteria. Procedures for this examination exist and were implemented. The weld inspection-personnel meet the' qualification requirement of ANSI N45.2.6.

Where NDE examinations were required, the examinations.were performed using personnel qualified to the requirements of SNT-TC-1A.

5. Comparison of AISC and NF Requirements (cont'd)

c. Examination and-Inspection (cont'd)

The weld examination requirements between NF and AWS are compatible since fillet welds are used for the auxiliary steel connections.

6. Summary The CPS classification of NF Boundary Jurisdiction is in compliance with the NF 1974 (Summer addenda) and is similar to the classification of many other nuclear plants under construction.

The auxiliary steel not classified as NF meet the requirements of the AISC Code and have been designed, constructed and examined in accordance with rules compatible with NF requirements.
