Attachment 1 DR-03-03-046 Task Order No. 003 SOW Modification 1 to Task Order 3 (J-3304) under Contract No. DR-03-06-046

Title:

Evaluation of the Technical Adequacy of New PWR Sump Design of the Millstone 2 Response to Generic Letter (GL) 2004-02 Technical Monitor: Leon Whitney, Office: 301/415-2869; E-mail: lewl @nrc.gov TAC Number: MC4694 PURPOSE AND NEED FOR THE MODIFICATION The original task order called for the evaluation/audit of the technical adequacy of the new PWR sump design at Indian Point 2 consisting of the examination of the plant's technical approach/solution to the emerging problem of chemical debris in the sump. The licensee decided to reassess the entire technical approach due to emerging chemical effect issues and will not have a decision on a revised technical approach to their corrective actions for Generic Letter 2004-02 until the beginning of December 2006. This decision conflicts with the scheduled December audit and, therefore, the NRC is unable to proceed with the scheduled work.

Instead, the Millstone 2 plant is being substituted and is thus the reason for this modification.

Because of the numerous changes to the Statement of Work: technical focus, level of effort, scheduled milestones, period of performance, travel requirements, etc., a new Statement of Work has been prepared.

BACKGROUND In June, 2003, the NRC identified Generic Safety Issue (GSI)-191, involving the potential for clogging of recirculation sump screens in pressurized water reactors (PWRs). Based on the findings of the GSI-191 ("Assessment of Debris Accumulation on PWR Sump Performance")

study conducted by the NRC Office of Nuclear Regulatory Research on ECCS suction/containment sump clogging in PWRs, the NRC staff issued a Safety Evaluation (SE) of a PWR sump design guideline report developed by the Nuclear Energy Institute (NEI) in conjunction with the PWR Owners group, and also issued Generic Letter (GL) 2004-02, "Potential Impact of Debris Blockage on Emergency Recirculation During Design Basis Accidents at Pressurized-Water Reactors." In response to the GL, and using the guidance approved in the SE, licensees are proceeding to resolve the GSI-1 91 issue for each PWR plant.

The NRC staff, through audit of licensee corrective actions in response to GL-2004-02, is reviewing the new sump strainer designs and their performance.

NRC staff has decided to audit the Millstone 2 Nuclear Power Station to verify and confirm that their new sump strainer performance is in compliance with the 10 CFR 50.46.

Attachment 1 - Page 2 OBJECTIVE The objective of this task order is to obtain engineering expertise from ARES Corporation to assist the staff in determining the technical adequacy of the GSI-1 91 Sump Clogging Issue analysis of the Millstone 2 Nuclear Generating Plant.

TECHNICAL AND OTHER SPECIAL QUALIFICATIONS REQUIRED One senior level mechanical engineer with extensive experience on PWR LOCA analyses and containment analysis. This includes "baseline" analytical areas such as LOCA break selection, debris generation, debris characteristics, debris transport (including the emerging area of sump and containment pool "near-field effect"), recirculation water hold-up volumes, strainer design and performance, strainer head-loss and vortexing, and ECCS and containment spray pump net-positive suction head (NPSH).

WORK REQUIREMENTS Tasks Completion Schedule

1. Travel to NRC Headquarters or the Millstone 2 site Two days after the near New London, Connecticut for a one day pre- meeting.

audit meeting with the licensee to become familiar with the licensee's new strainer design and approach.

Prepare a trip report.

2. Based on the requirements defined in NRC Safety One week prior to the Evaluation Report for GSI-1 91, review the new audit week trip Millstone 2 sump strainer baseline analyses. Identify scheduled for any apparent analytical deficiencies and any need January 22, 2007.

for additional information for review during the audit.

Submit a technical letter report.

3. Prepare for and travel to the Millstone 2 Nuclear Power Station to assist the NRC in the conduct of an audit of the assigned "baseline" technical areas. Based on NRC requirements referenced above, and information gathered during the audit, prepare a technical letter report.

a. Draft. Two weeks after the audit week trip.

b. Incorporate NRC comments and prepare the final report. One week after receipt of NRC comments.

LEVEL OF EFFORT The estimated level of effort in professional staff days apportioned among the tasks are as follows:

Tasks Level of Effort (days)

1. 3.0

2. 3.5

3. 17.5

Attachment 1 - Page 3 Total 24.0 PERIOD OF PERFORMANCE The projected longest period of performance is three months from authorization to start work.

DELIVERABLES Technical Reporting Requirements NOTE: All reports are to be submitted electronically using WordPerfect X3 (Font Arial regular 11 point) or compatible software program to the Technical Monitor with a copy provided to the Project Officer. In all correspondence, include the following information: JCN No., Task No., the applicant, the facility, TAC No., and NRC/NRR Branch.

1. At the completion of Task 1., submit a technical letter report that contains a brief description of the purpose of the trip and any major observations.

2. At the completion of Task 2, submit a technical letter report that identifies any analytical deficiencies in the areas of the new Millstone 2 sump strainer baseline analyses and the need for additional information for review during the audit week.

3. At the completion of Task 3., submit a technical letter report, draft and final as appropriate, that contains a detailed technical adequacy evaluation of the licensee's new sump clogging analysis (corrective actions in response to GL 2004-02), including "baseline" analytical areas such as LOCA break selection, debris generation, debris characteristics, debris transport (including the emerging area of sump and containment pool "near-field effect"), recirculation water hold-up volumes, strainer design and performance, strainer head-loss and vortexing, and ECCS and containment spray pump net-positive suction head (NPSH). Provide a list of any outstanding issues ("open items") with the basis or bases clearly articulated, including the significance of these outstanding issues relative to a conclusion of licensee GL 2004-02 corrective action adequacy.

MEETINGS AND TRAVEL One one-person, three day trip to either NRC Headquarters or the Millstone 2 reactor site near New London, Connecticut; assume New London for purposes of preparing a cost estimate.

One one-person, six day trip to the Millstone 2 reactor site near New London, Connecticut.

NRC-FURNISHED MATERIALS The licensee's submittal material will be made available during the meeting with licensee (if scheduled) or otherwise provided to the contractor in advance of the audit week. The submittal material, provided at the meeting with the licensee or by mail via the Technical monitor, will be provided at least two weeks before the onsite audit week.

OTHER APPLICABLE INFORMATION License Fee Recovery The work to be performed under this task order is not licensee fee recoverable.

Assumptions and Understandings It is assumed that contractors will have all of the required documentation, reports, etc. necessary to perform the work at least two weeks prior to the audit.

The pre-meeting with the licensee, Task 1, has not been confirmed with the licensee but is provided with the scope and the estimate in the event that a pre-meeting is held; for purposes of the cost proposal, assuming the trip is to New London. The level of effort assumed for Task 1 is based on one day travel to the NRC or Millstone 2 reactor site, one day of meetings, one day of return travel and report writing.

The level of effort assumption for Task 2 is based on a three and a half days review of the licensee submittal including development of a one or two page report.

The level of effort assumption for Task 3 is based on one day travel to the Millstone 2 reactor site, five days for the audit, one day of return travel, and ten and a half days for completion of the technical letter report and incorporation of NRC comments.
