SUBJECT:

SEABROOK STATION, UNIT NO. 1 - DRAFT REQUEST FOR ADDITIONAL INFORMATION (RAI), CONVERSION TO NEI 99-01, REVISION 4, EMERGENCY ACTION LEVEL BASIS (TAC NO. MD3927)

The attached draft request for additional information (RAI) was transmitted by facsimile on June 26, 2007, to Mr. Gary Kilby, at FPL Energy, Seabrook, LLC (FPLE). This draft RAI was transmitted to facilitate the technical review being conducted by the Nuclear Regulatory Commission (NRC) staff and to support a conference call with FPLE in order to clarify certain items in the licensees submittal. The draft RAI is related to FPLEs January 31, 2007, which requested to implement the Emergency Action Levels contained in the Nuclear Energy Institute document, NEI 99-01, Methodology for Development of Emergency Action Levels Scheme, for the Seabrook Station, Unit No. 1.. The draft questions were sent to ensure that the questions were understandable, the regulatory basis for the questions was clear, and to determine if the information was previously docketed. Additionally, review of the draft RAI would allow FPLE to determine and agree upon a schedule to respond to the RAI. This memorandum and the attachment do not represent an NRC staff position.

2. Explain why the ODCM values are not included in EAL 2.
3. 3rd paragraph of Bases: How will you make sure that this EAL is declared if release start time is unknown or when it is determined that the release will exceed 60-min?

3 AU2 Explain why the actual indicators are not included in EAL 1a or include the indicators.

4 AA1

1. EAL 1a and 1b both have a 15-min component. Can this be implied to mean 30 minutes? Is the 1b 15-minute component required? Explain.
2. Explain why the ODCM values are not included in EAL 3.
3. 3rd paragraph of Bases: How will you make sure that this EAL is declared if release start time is unknown or when it is determined that the release will exceed 60-min?

5 AA3 EAL 2: The use of the term UNPLANNED is inappropriate as defined in the 1st paragraph of the Bases. Correct discrepancy or justify.

8 CA4 EAL 4: Is 10 psig within the calibrated range of the instrumentation used for this? What is the scale of the instrumentation?

9 CS2 EAL 2: Does the use of the term COMBINATION imply that you need more than one of these indicators to make the declaration? Justify or correct.

10 CG1

1. EAL 2: Does the use of the term COMBINATION imply that you need more than one of these indicators to make the declaration? Justify or correct.
