Within the LER we indicated that by December 2,1997, an administrative procedure would be developed to coordinate the containment isolation valve leak testing requirements of 10 CFR 50 Appendix J with the Section XI Inservice Test Program requirements of the American Society of Mechanical Engineers (ASME)

Code.

ASME Section XI subsection IWV, titled " Inservice Testing of Valves in Nuclear Power Plants," paragraphs IWV-3426 and IWV-3427 require that CIVs be repaired or replaced when the leakage exceeds the maximum leakage limits established by the owner for the valve, or exceeds the value determined from the leakage rate equations given in paragraph IVN-3426. Operations surveillance testing procedures ensure that corrective actions will be implemented if allowable leakage limits are exceeded. This meets the technical basis for the commitmer' made within the LER.

. B16889\Page 2 l 4 i The addition of an administrative procedure to link the Appendix J and Section XI programs is an enhancement to the controlling site document currently used to perform the Appendix J Program at each unit. Additional time is necessary to ensure that the administrative procedure will encompass the needs of each of the Millstone units and define how the programs are implemented and maintained at the site.

Our revised commitment date for developing the administrative procedure is .

provided in Attachment 1.
