Project No. 9W 100:
- Docket No. 80 423 Northeast Nuclear Energy Company
- Millstone Nuclear Power Station, Unit No. 3 Independent Corrective Action Vestfication Program i
United States Nuclear Regulatory Commission Attention: Document Control Desk
- - Washington; D. C. 20555
- The Nuclear Regulatory Comr,)ission staff has requested that Sargent & Lundy (S&L) prepare and submit on the docket a report on the status and expected completion of the Millstone Unit 3
- ICAVP every two weeks. This report covers the period ending 11/07/97.
1 STATUS The slides normally used durin0 the monthly ICAVP status meetings have been updated to -
4
- provide the status through 11/07/97 and are enclosed. A summarf of that information is highlighted below:
Ilsr_1 Four of the five S&L Review Groups have work scope in the Tier 1 activities. The System Review Group (SRG) has essentially completed their review of the service water (SWP) and the containment spray systems (QSS/RSS), with the exception of the modifications. The additional
~ modifications and calculations for these systems that are currently being finalized by NU still i
need to be reviewed. - SRG work is progressing at an accelerating rate for the other sysiem -
groupings, HVX and DGX, and is approximately 46% complete. Similarly, the Confguration
' Review Group (CRG) has completed the walkdowns of the SWP and QSS/RSS syshns.- CRG
' activities are approximately 25% complete fv the HVX ard DGX system groupings.
t Operations & Maintenance and Toming Review Group (ORG)is also essentially P nplete with F
the SWP and QSS/RSS systems, with the exception of *he modifications discussed above.
- ORG is approximately 50% complete with the HVX and DGX system groupings.
t Programmatic Review Group (PRG) activities for Tier 1 include the corrective action document,g reviews and the recently added scope to review the Desi n Discrepancy Reports (DDRs). The 0
l
~
corrective action document review is approximately 95% complete; however two signifx: ant issues and their associated activities must be resolved and completed. As discussed in recent 9711130315 971110 PDR ADOCK 03000423 P

Unite'd States Nuclear Regulatory Commission November 10,1997 Cocument Control Desk Project No. 9583-100 Page 2 conference calls with NU and the NRC staff, there are approximately 100 CA documents for w5ich NU has not completed their processing. This means that they are not currently available for S&L to review. S&L is currently revit wing this list of CA documents against the most recent NU 1CCFR50.54(f) response letter to verify how many of these documents are deferred until after restart. A discussion on how to handle the remainder with respect to the completion of the (ther Tier 1 activities will be held vdth the NRC Staff. The other issue involves the NRC's intent for S&L in review the implementation activities for certain types of the Tier 1 corrective actions, such as calculations, evaluations, modifications, and other similar engineering functions. S SL is corrently developing the scope of ti.is work and will respond to the NRC by the week of 11/17/97.
Tlie DDR review is in process and progresslag satisfactnrily.
Based on the above discussion the expected completica for the Tier 1 review activities is 12/15/97. Please note that as a result of the additional modifications on the RSS system, we no longer have a schedule difference on Wave 1 and Wave 2 syMems.
.TitL2 The Tier 2 review being performed by the S&L Accident Review Group (ARG) is essentially complete. Only three critical characteristics remain to be verified. They will be completed as soon as the remaining information from RFis 530 and 689 is received. We expect to be complete by 11/14/97 based on NU's schedule for providing the information.
Titta The Tier 3 review being performed by the S&L Programmatic Review Group (PRG) is also essentially complete. Some specific information on four RFis is expected this week and will allow completion by 11/14/97, However, there are also 11 CA documents from the NRC selected sample for which NU has not completed its processing, which may impact the completion date.
Discreoancy Reoorts The last three slides from the enclosed status summary provide details on the preliminary DRs, the NU provided rosolutions, and the S&L review of those resolutions, in addition, a chart is attached which tracks the DRs and the resolution rate.
