Meeting Summary July 30,1997 Parsons Power Group Inc.

Waterford, CT

Subject:

Parsons Power presentation of system boundaries to NNECo Millstone Unit 2 ICAVP Docket 50-336 On July 30,1997, Parsons Power Group Inc. (PPGI) participated in a publicly observed meeting with the U.S. Nuclear Regulatory Commission (NRC) and NNECo. The pnmary purposh of the meeting was to present the system boundaries for the selected systems as part of the Millstone Unit 2 Independent Corrective Action Verification Program. A listing of primary attendees is provided as Enclosure 1.

PPGI presented their approach for the system boundary definition process. The boutdary definition -

process was followed by a detailed discussion of the boundaries for the Auxiliary Feedwater System -

(AFW) system (including the Condensate Storage Tank) and the High Pressure Safety injection System (HPSI) system (including the Refueling Water Storage Tank). It was noted that the determmation of the system boundaries was functionally driven and not limited by administrative interfaces.

Seven copics of the completed boundary packages were provided to the NRC and three copics were provided to NNECo. De boundary package included highlighted, marked-up interface drawings (P&ID's) and one-lines) of each of the selected systems,. as well as a system boundary booklet which included the boundary process description; interface type drawings; mechanical and electrical /l&C interface matrices;

- and Auxiliary FW/ CST and MFSI/RWST system function infonnation, simplified P&lD's, and system interface lists, f

During the presentation Parsons confirmed:

the review of electrical interfaces would include the power source e

- RPS & ESAS is reviewed as a " black box" Instrument sensor review includes process.

e

' Enclosure 2 prosides a listing of all interfacing systems for the AFW and HPSI. At the meeting 101.

specific interface points were identified for th? AFW system and 175 interface points were identified for HPSI. NNECo agreed to identify those interfaces that are not ready for Parsons resiew due to in progress NNECo CMP activities. NNECo identification would be complete by August 4 to allow Parsons l assignment of" placeholder ". Parsons will review " placeholder" interfaces when NNECo indicates they have completed CMP discovery.
