Subject:
Duke Power Company Catawba Nuclear Station, Unit 1 Docket No. 50-413 Request for Additional Information (RAI)
Request for. Relief from 1989 edition of ASME Boiler' i
and Pressure Vessel Code,Section XI.
j Serial No. 96-04 i
4 Re:
Letter from NRC to William R.
McCollum dated March 7,
1997, Request for Additional Information I
d The following response is provided to address the questions submitted by the subject RAI.
Each question is restated below with'the response following.
A.
Based on the initial review of the licensee's submittal, i
the staff has concluded that either (a) the appropriate paragraph of the regulations has not been cited, or (b) the regulatory basis has not been adequately supported.
j-Request for Relief 96-04 was submitted pursuant to i
10CFR50.55a(a) (3) (ii), but no burden or undue hardship j
has been presented.
This request should be reviewed for the correct paragraph of the regulations to ensure that the request is evaluated in accordance with the
/ /
appropriate criteria, as discussed below.
i
[
The regulations provide that'a licensee may propose an alternative to the Code of Federal Regulations or the code /
requirements in accordance with 10 CFR 50.55a (a) (3) (i) or 10 CFR 50.55a (a) '(3) (ii).
Under 10 CFR 50.55(a) (3)
(i), the proposed alternative must be shown to provide an acceptable level of quality, i.e.,
essentially, be equivalent to the original requirement in terms of quality i

- MMMMMpq i
9705140038 970505 PDR ADOCK 05000413 P
Document Control Desk Page 2 May 5, 1997 and safety.
Under 10 CFR 50.55a (a) (3 ) (ii), the licensee must show that compliance with the original requirement results in a hardship or unusual difficulty without a compensating increase in the level of quality and safety.
Examples of hardship and / or unusual difficulty' include, but not limited to, excessive radiation exposure, disassembly of components solely to provide access for examination, and development of sophisticated tooling that would result in only minimal increase in examination coverage.
A licensee may also submit a request for relief from ASME requirements.
In accordance with 10 CFR 50.55a (g) (5)
(iii), if a licensee determines that conformance with certain Code requirements is impractical for its facility, l
the licensee shall notify the Commission and submit, as 1
specified in Section 50.4, information to support that determination.
When a licensee determines that an 5
inservice inspection requirement is impractical, e.g.,
the examination is limited by physical restrictions and the j
component would have to be redesigned or replaced to enable inspection, the licensee should cite 10 CFR 50.55a (g) (5) (iii).
The.NRC may, giving due consideration to j
the burden placed on the licensee, impose an alternative examination requirement.
l
Response
i.
l Request for Relief 96-04 was submitted on December 12, 1996 pursuant to 10CFR50.55a (a) (3) (ii).
This was in error and should have been submitted under 10CFR50.55a (g) (5) (iii).
100% coverage of the subject welds was impractical because of single-sided access, due to pipe-to-valve configuration and austenitic weld metal.
B.
Section XI, Appendix III, Paragraph III-4420, Reflectors Parallel to the Weld Seam, requires examination coverage in two beam path directions to detect reflectors parallel to the weld seam.
This can be accomplished by either scanning from two sides of the weld, or by using a sufficiently long beam path to provide two-directional coverage from one side of the weld.
The requirement for two-directional axial scan coverage should also be reflected in the coverage calculations.
However, the coverage calculations provided
l j
Document Control Desk Page 3 a
May~5, 1997 l
1 with the licensee's submittal only include scan coverage.in I
one axial direction (with two angles) and it appears that the second axial direction was not included in the l
calculation.
As a result, the calculated coverage may be 1
overstated.
Provide a discussion regarding the examinations I
performed in the axial direction (s) and how the coverage was calculated.
i Responses Reference to Appendix III in Parts III, IV, and VI of j
Request-for Relief 96-04, dated December 12, 1996 was an
-error. to this letter is Revision 1~to Request for Relief 96-04, denoting the corrected reference of ASME Section XI.

System / Component (s) for Which Relief is Requested:
i l
ASME Section XI Code Class: 1 Examination Category: B-J Circumferential Piping Welds - Safety Injection System j
Weld Number Item Number 1 nil 48-10 B09.011.163 e
1N1148-11 B09.011.164 4
ll.
Code Requirement:
j ASME Section XI,1989 Edition, Examination ( ~
gory B-J Pressure Retaining Welds In Piping, Table IWB-2500-1, Figure ? o nber IWB-2500-8. Item Number B09.011 requires a volumetric examination ol' essentially 100% of the weld length s
and adjacent base. material for all piping welds. Duke Power Company, with NRC approval, has adopted Code Case N-460 which defines " essentially 100%" as greater 4
than 90% coverage.
i 111.
Code Requirement from which Relief is Requested:
Relief is requested for the above identified Class 1 Circumferential Piping Welds from meeting the coverage requirements as defined in ASME Section XI, Figure IWB-2500-8, Examination Volume C-D-E-F.
Request for Relief Serial No. 96-04
~
Revision 1l Page 2 of 4 IV.
Basis for Relief:
During the ultrasonic examination of the welds shown in Attachment 1, coverage of the required examination volume as modified by Code Case N-460 could not be obtained. Causes of these limitations are single sided access due to pipe-to-valve i
configuration and austenitic weld metal. Where possible, a combination of angles and wave modes were used to maximize the coverage obtained. The weld and base metal at the component inside surface was covered from at least one direction with a minimum of one angle. The examinations were performed in accordance with ASME 1
Section XI, Appendix I and Appendix Vill,1992 Edition with the 1993 Addenda as allowed by Request for Relief 95-GO-003, dated September 12,1995.
V.
Alternate Examinations or Testing:
No additional examinations are planned during the current interval for Weld ID Numbers INIl48-10 and INil48-11. The use of radiography as an alternate j
volumetric examination method for Weld ID Numbers INIl48-10 and 1 Nil 48-11 is not feasible due to component thickness, geometric conngurations, and restrictions from physical barriers which prohibit access for the placement of source. image quality indicators, film, etc. Duke Power Company will continue to use Appendix VIII qualified ultrasonic examination procedures for detection of far side Haws, when examining them h austenitic weld metal.
VI.
Justification for the Granting of Relief:
Although the examination volume requirements as denned in ASME Section XI, Figure IWB-2500-8, Examination Volume C-D-E-F could not be met, the amount of coverage obtained for these examinations provides an acceptable level of quality and integrity. The inside surface of the pipe, within the required examination volume, received 100% coverage in the axial direction. If a surface connected circumferential flaw had been present,it would have been detected. For results of examinations, reference Attachment 2, pages 6 of 9 and 9 of 9. The welds in question connect the first and second check valves off the reactor coolant system and are one of the four paths for ECCS injection. in the unlikely event of their failure Duid would leak from the Cald Leg Accumulator (CLA) to the containment building floor. A drop in level from an accumulator with a corresponding increase in sump inputs would occur. An eventual alarm in the control room for CLA level would require action per Technical l
Request for Relief Serial No. 96-04 Revision 1l Page 3 of 4 1
Specification 3 / 4. 5.1. The limit on unidentified leakage is 1 gpm from sump input and is monitored by OAC point alarms. The Technical Specification 3 / 4. 6. 2 would be enforced if the unidentified leakage went above I gpm. These alarms would indicate a problem and allo,; adequate response time before the current margin in i
injection flow (Actual to test acceptance criteria) indicated by the ECCS flow balance testing is surpassed. Based on these evaluations,it is Duke Power Company's opinion that the limited coverage will not endanger the health and safety of the general public. Duke Power Company will perform UT examinations to the extent practical using procedures and personnel qualified in accordance with ASME Section XI, Appendix VIII,1992 Edition with 1993 Addenda.
