' Inservice Inspection (ISI)

.The inspector reviewed procedures, interviewed licensee / contractor personnel and reviewed records to determine whether the licensee's program pertaining to the ISI is complete and in conformance with regulatory requirements and the licensee's commitments, as indicated- below. The applicable Code for ISI is ASME Boiler and Pressure Vessel (ASME B&PV)

Code Section XI 1977 Edition, Summer (Winter) 1978 Addenda. The plant,

which commenced commercial operations January 1,1984, is in the first 40 month period of the first ten year ISI interval (January 1,1984 to December 31,1993).

ISI for the upcoming outage will in part be performed by Universal Testing Laboratories, Inc. (UTI) of Ceder Grove, New Jersey under the umbrella of the UTI QA Program as modified by a " Memorandum of Understanding" dated January 22, 1987. Eddy Current Examination of the steam generators will

, be performed by Babcock & Wilcox (B&W) under the umbrella of' the B&W QA l Program. Mechanized ultrasonic examination of the reactor vessel will be performed by Combustion Engineering (CE) under the umbrella of the CE QA Program, Review of Program (73051)

(1) Program Organization The inspector reviewed the licensee and ISI contractor's QA programs to verify the following: procedures for the mainte-nance of required ISI records; QA review includes assurance that plans and procedures have been reviewed by appropriate personnel and meet regulatory requirements; procedures are established for the corrective action of conditions adverse to quality as detected during examination, including provisions to preclude repetition of such adverse conditions; audits or surveillance of ISI activities are conducted by qualified QA personnel to verify compliance with the ISI program; and procedures are established to effectively oversee contractor activities concerned with

SCE&G review. The ANII will be provided the procedures after the resolution of the SCE&G ,

comment The inspector noted the following '

discrepancies:

  • UTL-VT-01, R0 does not provide specifi acceptance criteria for VT-1 and VT-4
  • UTL-MT-01, R1 does not address maximum temperature of 600 F as required by ASME V, T-725-1; does not require " adequate contrast" of particles with the background as required by ASME V T-725.1; and does not provide specific acceptance criteri * UTL-PT-01, R1 does not provide specific acceptance criteri i
  • UTL-PT-02, R0 does not address the prohibi-tion of fluorescent liquid penetrant exami-nation after a visible examination as i required by ASME V, T-630(c); fluorescent I examiners shall be in darkened area for at ;

least five minutes prior to performing the I examination to enable his eyes to adjust to dark viewing and if examiner wears glasses or lenses, they shall not be photo ;

sensitive. This is contrary to good I industry practice. The ASME has added this l as a requirement to the 1983 Edition of Code Section V; and does not provide specific acceptance criteri l l

87-07-01: "UTL Procedure Discrepancies."

b) The inspector noted that B&W procedure ISI-424, Rev. 9 specifies ASME Code Case N-401. The inspector discussed the same with the licensee who indicated that they were in fact intending to use the code case which permits the use of digital data collection for eddy current examina-tions. The licensee was however unable to provide objective quality evidence of approval for the use of Code Case N-40 This matter will be identified as Inspector Followup Item 50-395/87-07-02: " Code Case N-401 Approval."

c) The inspector was informed that the CE procedures for the examination of the reactor vessel would not be on site until March 6, 198 Pending NRC review of the CE reactor vessel examination procedures this matter will be identified as Inspector Followup Item 50-395/87-03: "Unavail-able CE Procedures."

d) The inspector found the following discrepancies in SCE&G N0E procedures:

  • T-NQCP-1 does not specify the year edition of SNT-TC-1 .

'

T-NQCP-2 and T-NQCP-3 do not address the prohibition of fluorescent liquid penetrant examination after a visible examination as required by ASME V, T-630(c); fluorescent examiners shall be in darkened area for at least five minutes prior to performing the examination to enable his eyes to adjust to dark viewing and if examiner wears glasses or lenses, they shall not be photo sensitive. This is contrary to good industry practice. The ASME has added this as a requirement to the 1983 Edition of Code Section V; do not define the examination area of interest; do not address the calibration or accuracy verification of the light meter used to verify the intensity of the ultraviolet; and do not specify the changes that require procedure requalifica-tion as stated in ASME V, T-68 The licensee indicated that would make appro-priate change Pending NRC review of the amended procedures this matter will be identified as Inspector Followup Item 50-395/87-07-04: "SCE&G NDE Procedure Discrepancies".

Within the areas examined, no violations or deviations were identified.

6. Inspector Followup Items (Closed) Item 50-395/84-31-02: " Stroke Time Limits" The inspector of record for Report 50-395/84-31 noted that the maximum acceptable stroke times specified for valves XVT-8149 A, B, & C by the licensee were 40 seconds. These are fast-acting air operated valves. Typically, such valves operate in under two seconds. The inspector informed the licensee that he believed that setting a 40 second maximum stroke time for such valves was almost meaningles This inspector looked further into this matter and found that valves XVT-8149 A, B, & C are among 52 valves of varying sizes and types that are listed in Table 3.6-1, " Containment Isolation Valves," of the TS, all of which have a specified maximum isolation time of 40 second Of the 52 valves, 40 valves have actual average closure times less than 10 seconds, and 38 valves have actual average closure times less than 5 seconds. The licensee stated that because the TS permit 40 seconds for isolation (the time to perform their safety function). They will use that value for ASME P&BV Code Section XI stroke time. The licensee further indicated that to select a value more restrictive than the TS requirements would set a bad precedent for the compan _ __ ____-_________- _ _ ________- _ ______

of Nuclear Reactor Regulation, dated April 11, -1985,. for docket '

No.'50-341. The inspector.has no further questions. This matter-is-considered close (0 pen) Item. 50-395/85-08-02:

.

This ' item concerns whether valves XVG- 9503A and B in the component cooling water system should be included in the inservice test'(ISI)

progra The licensee claims that these valves were not included. in the ISI-program based on discussions which occurred during meetings held on

~

February 24-25, 1982, between NRC and SCE&G regarding the IST program for pumps and valves. This meeting was documented .in a March 16, 1982,, letter to the licensee. The licensee contends that inclusion of. the subject valves and other valves of similar function which do L not receive an automatic ESF signal represents a departure from 'a previous NRC interpretatio The March 16, letter indicates " Listed Valves" have no - safety function. Therefore, it follows that the " Listed Valves" would not be required to be included in the .ISI program. Unfortunately, the March 16,1982, letter does not identify the " Listed Valves." The licensee presented this inspector a photocopy of .an- unsigned hand-written document; apparently the notes from which the March 16, 1982 letter was written. This document indicates that Valves ~XVG 9503A and B are 'among the " Listed Valves." Pending the legitimization of the unsigned photocopy of handwritten notes, this matter remains ope (Closed) Item 50-395/86-18-02: "QA Auditor Qualification" NRC Report No. 50-395/86-18 noted that the licensee's procedure for qualification of QA auditors was cancelled effective August 1.1986, and its replacement was in preparation. The licensee has issued Al-205 Revision 0, " Quality Assurance Personnel Indoctrination and Training" effective October 22, 1986. The inspector has no further questions. This matter is considered closed.
