72  ISI Inspection of Code Class 1, ' 2 and 3 Pumps And Valves This item was discussed from the point of view of what NRC requires and by when.
It was not anticipated that this item would be closed out at this time. R Bosnak discussed intersystem LOCA which was identified in WASH 1400. NRC's revised SRP 3.9.6 Appendix A and NUREG 0677 identify what NRC will be looking for regarding intersystem LOCA.
It was suggested that Pump and Valve PSI /ISI be broken out from the rest of the.ISI program and given some priority (ie, possibly submitted 12 months prior to fuel load) so that MEB has sufficient time to review the exceptions to ASME Section XI. If the pump and valve ISI program cannot be completed 12 to 6 months prior to fuel load, a list of areas where LP&L requires relief will be helpful to MEB.
                             ~
NRC indicated that the ISI procedures would not be required for them to perform their review under SRP 3.9.6.

New Item 1            During the meeting, NRC's R Bosnak introduced a new item concerning code stamping of ASME Code Class 3 components. Mr Bosnak stated that LP&L's recent letter to NRC (LPL 14099, dated June 2., 1980) did not adequately address all concerns raised in NRC's letter to LP&L from R L Baer (Dated February 7,1980) .        In summary, while the physical application of an N-symbol on a Class 3 component is not mandatory, this required that Quality Group C (ASME Class 3 components) be constructed in a manner equiva-lent to that obtained by otherwise fully complying with the ASME Code.        ASME Code construction require mandatory third party inspection and accompaning code data reports.

Page 16 of 17 New Item              Commitments 1 (cont'd)         Mr Bosnak stated to the best o'f his              '
knowledge that waterford 3 was unique in-the industry in this matter.
In later discussions, Mr Bosnak advised that LP&L should provide the following information for the Emergency Feedwater and Component Cooling Water Systems, so that this matter could be evaluated jointly by I&E and NRR.
Item 1 - Identify all Class 3 components and their manufacturer.
Item 2 - State that the manufacturer has the proper ASME Certificate of Authorization, including the certificate number, and the period for which the certificate is valid.
Also, the date of fabrication of the complete component should be identified.      (This will indicate whether or n'ot the component was manufactured during the period in which the Certificate of Authorization was valid).
It.em 3 - Submit the certificates of compliance or certified material test reports.
It,e,m 4 - Submit code data reports with third party inspection sign-off if avail-able.
LP&L questioned Mr Bosnak since Regulatory Guide 1.26 (Revison 2, dated June 1975) permits not applying the ASME code N-symbol on Class 2 and 3 components. Mr Bosnak advised that this was, not intended to permit the utility to construct these components to a system not e'q'uivalent in all elements to that of the ASME System. A vital element of the ASME System is t.hird party inspection by an authorized Nuclear Inspector. Regulatory Guide 1.26 only eliminates the need to physically stamp the components.
Ali other code requirements are still required.       i 2A               Augmented ISI Program for Pipe included in Break Exclusion zones.                                i November submittal will contain applicants commitment and indicate exceptions with justification.       This will be placed in FSAR Sections 3.6 and 6.6.8 per NRC's request.
