REQUEST FOR ADDITIONAL INFORMATION DUANE ARNOLD ENERGY CENTER DOCKET NO. 50-331(TAC NO. MD6020)

In reviewing the FPL Energy Duane Arnold, LLC submittal dated June 29, 2007 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML072040245), related to request to change Technical Specification (TS) Sections 3.7.4 and 5.5.13 based on model text from TS Task Force (TSTF), TSTF-448, for Duane Arnold Energy Center, the Nuclear Regulatory Commission (NRC) staff has determined that the following information is needed in order to complete its review:

1. The licensee stated that the wording for TS 5.5.13.d differs from the model wording used in TSTF-448. More specifically, the wording has been changed to specify that the Control Building (CB) pressure is measured relative to the outside atmosphere instead of relative to all external areas adjacent to the CB Envelope.

It is the NRC staffs understanding that the primary purpose of measuring differential pressure (dp) relative to all external areas adjacent to the control room envelope (CRE) boundary is to determine the direction of air flow across the boundary of the CRE. It is not clear how measuring dp relative to outside atmosphere will provide any meaningful information that can be used to determine the direction of air flow across the CRE boundary.

Therefore, the NRC staff is requesting that the licensee measure dp relative to all external areas adjacent to the CRE boundary, as stated in TSTF-448, or explain in detail how measuring dp relative to outside atmosphere will provide information that can determine the direction of air flow across the CRE boundary.

2. The license referenced a previously performed hazardous chemical evaluation as docketed in a letter to the NRC dated January 28, 2005 (ADAMS Accession No. ML050390308). This evaluation found that there are no on-site or off-site stationary or mobile hazardous chemical sources that threaten CB habitability.

What program or programs currently exist at Duane Arnold Energy Center to ensure that the licensee revisits the issue of on-site and mobile sources of hazardous chemicals on a periodic basis?
