| | Two examples of Violation 86-42-01 were cited in Inspection Report 86-42 pertaining to ASCO solenoid valves (one on seismic qualification, one on environmental qualification). These issues resulted from two unresolved items identified in Inspection Report 85-45 and later reviewed in Inspection Report ' |
| FEB 2 61987 Tennessee Valley Authority EATTN: Mr. S. A. White Manager of Nuclear Power 6N 38A Lookout Place 1101 Market Street Chattanooga, TN 37402-2801 Gentlemen:
| | 86-01. These items were upgraded to violations in Inspection Report 86-4 TVA responded to the violation on October 24, 1986, by admitting the first example of 86-42-01 pertaining to the seismic qualification, but denied the second example pertaining to environmental qualification. A request for technical assistance was sent from myself to Brian Grimes on December 5, 1986, to evaluate the environmental qualification issues addressed in Report 86-42 as Violation 86-42-01 and Unresolved Item 86-42-0 George Hubbard evaluated these issues during his inspection reported in Inspection Report 86-70 on December 12, 1986, and addressed these issues in a Grimes memorandum dated January 16, 1987, which concluded that the violation was valid. We issued a response to TVA's denial of October 24, 1986, based on the January 16, 1987, Grimes' memorandum refuting TVA's denial an February 26, 1987 TVA on April 6,1987, again denied the violation. George Hubbard has recently discussed the second denial with TVA. In light of this second denial, please evaluate this EQ issue from a technical standpoint and determine if TVA's denial is valid based on the NRC's EQ polic If you consider that TVA's denial is not valid, please prepare a draft response to TVA that represents how you believe the NRC should respond to this denia It is requested that you respond to this memorandum by May 22, 1987, to support completion of Sequoyah inspection activitie ORIGINAL.

| E5L .Io 357 ENCLOSURE Your denial of Violation 50-327,328/86-42-01 (Example 2), is based on the grounds that the work instructions used for installation of the solenoid valves were adequate; however, this is questionable in light of the fact that the vendor bulletin (not pr.rt of the installation package) for the ASCO model 8316 valves for nuclear power plants, documents that the four valve bonnet (end plate) screws have torque values of 95 plus or minus 10 inch pounds in a crisscross manne Since the vendor was specific with regard to torquing values and the tightening pattern for the bonnet screws, these items are considered significant and should be followed. In addition, it is understood from informal discussions with Sequoyah that they have actually gone back arid tightened the bolts to the vendor value You further state that the environmental qualification of the valve was not affected by the reconfiguration of the mounting support as performed under work package 11806, since the area of the valve that would have been affected by the improper installation of the bolts is internally isolated from the portion of the solenoid valve which contains that electric coil. Since the valve is environmentally qualified as a whole device, this argument is considered not applicable to the situatio In fact, in a letter to Dr. J. Nelson Grace, RII Administrator, from R. L. Gridley, Director, Nuclear safety and Licensing, Subject: Watts Bac Nuclear Plant Units 1 and 2 - Improperly Installed Solenoid Valves - WBRD-50-390/85-52, WBRD-50-391/85-14 - Final Report, dated May 2, 1986, TVA states that ASCO solenoid valves are supplied to them as a complete qualified package with supplier-imposed instructions which must be followed to ensure that their application in the plant conforms with qualification tests. The position taken in this letter seems to be contrary to the TVA Sequoyah position taken in the denial of the violation. The NRC concurs with the original TVA position dated May 2,1986, and disagrees with the Sequoyah position that the environ-mental qualification of the valves was not degraded. We, therefore, believe the violation occurred as state T !. .;r

,. N MAY 0 41987 MEMORANDUM FOR B. D. Liaw, Assistant Director, Technical Review Division of TVA Projects, Office of Special Programs Gary G. Zech, Assistant Director, Inspection Programs,
~
FROM:
Division of TVA Projects, Office of Special Progre.ms SUBJECT: ASCO SOLEN 0ID VIOLATION 86-42-01
.
Two examples of Violation 86-42-01 were cited in Inspection Report 86-42 pertaining to ASCO solenoid valves (one on seismic qualification, one on environmental qualification). These issues resulted from two unresolved items identified in Inspection Report 85-45 and later reviewed in Inspection Report '
86-01. These items were upgraded to violations in Inspection Report 86-4 TVA responded to the violation on October 24, 1986, by admitting the first example of 86-42-01 pertaining to the seismic qualification, but denied the second example pertaining to environmental qualification. A request for technical assistance was sent from myself to Brian Grimes on December 5, 1986, to evaluate the environmental qualification issues addressed in Report 86-42 as Violation 86-42-01 and Unresolved Item 86-42-0 George Hubbard evaluated these issues during his inspection reported in Inspection Report 86-70 on December 12, 1986, and addressed these issues in a Grimes memorandum dated January 16, 1987, which concluded that the violation was valid. We issued a response to TVA's denial of October 24, 1986, based on the January 16, 1987, Grimes' memorandum refuting TVA's denial an February 26, 1987 TVA on April 6,1987, again denied the violation. George Hubbard has recently discussed the second denial with TVA. In light of this second denial, please evaluate this EQ issue from a technical standpoint and determine if TVA's denial is valid based on the NRC's EQ polic If you consider that TVA's denial is not valid, please prepare a draft response to TVA that represents how you believe the NRC should respond to this denia It is requested that you respond to this memorandum by May 22, 1987, to support completion of Sequoyah inspection activitie ORIGINAL.
