- From time-to-time the Assessment Team has stated that the completions of underpinning piers, from excavation to load transfer, should be accomplished in a more t'imely manner. This item is still,of concern to the Assessment Team, although some improvement has taken place and Quality has not been impacted.
Mr. W. E. Kilker presented a description of the major underpinning activities during the previous month. Highlights follow:
- The installation of the Pier 8 grillage beams on the east and west ends of the Auxiliary Building was the major underpinning activity during the month. They were installed in accordance with project procedures, and the Assessment Team was particularly impressed with the teamwork i
demonstrated during the load transfer to the beams.
- Progress was made in obtaining. access for underpinning activities through the Utility Access Tunnels. The soil stabilization by grouting is being effectively accomplished. Grout takes are high.
- Outstanding NCRs on the reinforcing steel for the BWST foundations have been resolved and. installation of the reinforcing steel has begun.
- At the SWPS the installation of the soldier piles is almost complete and initial testsof the dewatering systems suggest that it may be more effective than anticipated.
- Miscellaneous activities have included installation of cathodic protection systems, removal of two 36 inch casings, piezometer installation and soil investigation work.
- During the installation of a piezometer there was an incident of drilling into a beam that extends from the Auxiliary Building. A stop work order was issued on drilling and the occurrence was investigated.
In the future, structural drawings will be reviewed, in addition to utility
Minutes of Meeting PAGE 4 drawings, before a drilling permit is issued.
- One NCR was issued during this period.
It concerned certification of QC supervisors.
This NCR has been closed.
- Five Work Activity Packages were reviewed and Assessment Team questions were satisfactorily resolved.
Questions and Answers
- Mr. J. J. Harrison (NRC) asked if Stone & Webster tracked commitments made by CPCo in closing open items from the daily meetings, for example, Item 52-14. A check by the NRC had shown that some six weeks after the commitment had been made the drawing had not been changed. Mr. W. E. Kilker (S&W) replied that Stone & Webster does not track an item after closing, but the item would be brought to CPCo 5ttention if the drawing were to be used for crnstruction without' the change being made.
R. A. Wells (CPCo) stated that if it is flagged on a formal quality document it would be tracked.
J. A. Mooney (CPCo) stated that he will check on the CPCo tracking process.
Mr. R. Landsman (NRC) canmented that a drawing with a detail noted as Non-Q had been identified and this also had not been corrected.
- Mr. J. J. Harrison (NRC) remarked that daily meeting notes indicated that an item on a drawing was only a suggested method and not a i
requirement and asked why it was shown on the drawing, if it is only a suggestion. Mr. W. E. Kilker (S&W) stated that the procedure associated with this item points out that it is a suggested method.
Mr. J. A. Mooney (CPCo) stated that he will check on-this item.
- Mr. J. J. Harrison (NRC) commented that in weekly report No. 49, the Assessment Team suggested a solution to possibly avoid problems with welding. This suggestion had also been made in weekly report No. 30.

Checklists have been prepared for 69 Project Quality Control Instructions (PQCIs) that are applicable to the verification phase of the CCP and for 40 other areas that hold special interest within the scope of the CIO but are not covered by PQCIs. These checklists are now being maintained current with revisions to base documents.
' Summary of Assessment Activities. Efforts were focused during the period on areas of particular concern to starting up the CCP. Assessment activities also took place for areas outside the CCP but within the scope of the CIO. These areas were the Spacial Systems Interaction Program (SSIP);
Heating, Ventilation, and Air Conditioning Program (HVAC); and the Nuclear
. Steam Supply System (NSSS) Seven Management Review Meetings and some
