vulnerable to erosion - corrosion attack. Currently, the licensee's program is in a developmental stage perd.'ng further changes in the EPRI Guidelines NP-3944, April 1985, " Erosion / Corrosion in Nuclear Plant Steam Piping: Causes and Inspection Guidelines" and '

"Single-Phase Erosion-Corrosion of Carbon Steel Piping" dated February 19, 1987, and the results of the inspection planned for the Fall 1988 refueling outag The inspector noted that the licensee's existing procedures for measuring erosion-corrosion, using ultrasonic examination do not require the mark;ng a permanent reference point for each band ins pec te Without such a reference point it is not possible to accurately find a specific location on a fitting at a later date.

J Without the ability to accurately find specific locations on a fitting, accurate determination of actual erosion-corrosion rates is not possible. The licensee indicated that permanent reference '

'

marking would be included in the examination procedure used during the planned Fall 1988 refueling outag This bulletin will be subject of future inspections and will remain open, b. (0 pen) NRCB No. 87-02: "Fastener Testing to Determine Conformance with Applicable Material Specifications" t

The bulletin requested licensees to review their receipt inspection requirements and internal controls for fasteners and independently determine, through testing, whether fasteners (studs, bolts, cap l screws and nuts) in stores at their facilities meet required l l mechanical and chemical specification requirement Supplements 1 and 2 to the bulletin requested licensees to,1) provide a list of j suppliers and manufacturers from which safety-related ferrous 1 fasteners 1/4 inch in diameter or greater, that may have been i purchased within the past ten years, and 2) provide similar i

infonnation for nonsafety-related fastener supplier ,

'

The inspector has reviewed South Carolina Electric and Gas (SCE&G) l letters of January 12, 1988 and July 20, 1988, and determined that )

the requested actions of the bulletin have not been acceptably a

addressed. The inspector held discussions with responsible SCE8G representatives, reviewed supporting documentation and observed representative samples of work to verify that the actions identified in the letter of response have been completed.

Action Item 3 of the Bulletin requires a selection of 20 nuts (ten j safety-related and ten nonsafety-ralated). The licensee selected seven safety-related and four nons .ety-related nuts. The above was i the result of an misinterpretation by SCE&G of the intent and l requirements of the bulletin, and a misunderstanding, by the NRC of l

the verbally transmitted reasons provided by SCE&G, for a reduction

in the number of nuts required to be sampled.

The inspector discussed the above with the licensee. NRC Region II management, and NRC NRR Management Responsible for this bulletin and

<

determined the following:

(1) 3CEaG acted in good faith concerning their selection of sample siz (2) The intent of the bulletin was to take a sample of ten each safety-related and ten nonsafety-related threaded male fasteners and ten each safety-related and ten each nonsafety-related nuts, for a total of 40 specimen (3) "Independent Testing" as used in this bulletin, means independent of the manufacturer / supplier and not independent of the licensee, provided that the licensee is independent of the manufacturer / supplier and has the facilities to perform the ;

necessary testin l l This Bulletin remains open, c. (0 pen) NRCB No. 88-02: "Rapidly Propagating Fatigue Cracks in Steam I

Generator Tubes" This bulletin established a requirement, for licensees having [

Westinghouse steam generators with carbon steel support plates, to t inspect and analyze the data from at least 3% of the total steam generator tube population for denting at the uppermost tube support plat The inspector has reviewed SCE&G letter of March 24, 1988, and 3 determined that the requested actions of the bulletin have been

) acceptably addresse The inspector held discussions with

] respnnsible SCE&G representatives, reviewed supporting documentation and observed representative samples of work to verify that the

actions identified in the letter of response have not been completed.

! The licensee indicated that Surveillance Test Procedure (STP) 404.901, d

"Steam Generator Tube Inspection," would be revised prior to performance of the next eddy current inspection currently scheduled

. for the Fall of 198 Further the licensee indicated that the 1 revision would initiate the following actions if denting is found in l l subsequent inspections and ensure compliance with item C of the '

bulletin: an enhanced primary-to-secondary leak rate monitoring '

J program will be initiated and, a program will be established to

{ minimize the probability of a rapidly propagating fatigue failur ! .

4 (0 pen) NRCB No. 88-05: "Nonconfoming Materials Supplied By Piping Supplies, Inc. at Folsom, New Jersey and West Jersey Manufacturing Company at Williamstown, New Jersey" This bulletin required licensees to submit information regarding l materials supplied Piping Supplies Incorporate (PSI) and West Jersey  ;

Manufacturing (WJM) Company and to take actions to assure that (1) rr.sterials comply with the American Society of Mechanical Engineers (ASME) code and design specification requirements or are suitable for their intended use and (2) replace such material Supplement 1, to this bulletin, provided additional information about PSI and WJM supplied materials, reduced the scope of the materials review, delineated actions licensee are required to take to identify materials, and clarified actions licensees are required to take once noncomplying materials have been identified. Supplement 2 to this bulletin modified the schedule for actions requested by the Bulletin and Supplement 1 of the Bulletin and provided additional information about materials provided by WJM, PS! and recently identified company, Chews Landing Metal Manufactures Incorporated (CLM). For full power licensee's, Supplement 2 to the Bulletin indicated, based on reported measurements and analytical results to date, that it is appropriate to suspend, temporarily, the field measurements, testing, records review, and the of Justifications for Continued Operations (JCOs) that p*eparation were requested by the Bulletin and Supplement 1 until further notice. Holders of full power operating licenses were required to report the results of their records review, testing, and analysis performed as of the date of Supplement 2 in accordance with the 120 day reporting requirements specified in Paragraph 1 of the Bulletin (May 6, 1988 Plus 120 days is September 3,1988).

The licensee has identified two Purchase Orders (P0s) which involved 17 items supplied by WJM and PSI. Of these 17 identified items, seven were installed in the system. Three of the installed items are inaccessible for inspection during plant operatio Of the remaining ten items, the licensee has located nine in the warehous The disposition of all 17 items including is contained in SCE&G's Nuclear Change Notice 2988. This bulletin will remain open pending NRC receipt and review of the licensee's response to this bulletin, e. Observations Relative to the inspection of the licensee's ections concerning the four bulletins discussed above, the inspector noted that the licensee aggressively investigated the matters covered by the bulletins and responded in a timely manner to the bulletins.

L Material Identification '

The licensee has procured a "Spectra Test" Model F, Optical Emission Spectrometer with the Argon pistol adaptor to facilitate the  !

dedication / analysis of ferrous and nonferrous materials for safety, i quality and nonquality-related use at the V. C. Summer station. The system consists of a light pistol with a 30 foot flexible umbilical tube '

- which transmits tiie light from the area to the mobile spectrometer. The spectrometer is 40 x 24 x 28-inch, 400 lb unit fitted with 10-inch j i pneumatic wheels. The mobility of the unit will permit its use in many parts '

of the plan t The inspector witnessed a demonstration of set-up calibration and analysis f i of a number of carbon steel and low lloy steel samples. The only f

! limitations noted by the inspector were the following: the accuracy of the analysis for carbon is some what less than for f other elements i

!

j the equipment will not perform an analysis for phosphornus or sulfur,
