The NRC Fukushima Near-Term Task Force {NTTF) Report (Reference 1) dated July 12, 2011, discussed the gap in capability for US commercial nuclear power plants to perform multi-unit dose assessments. In January 2013, the Nuclear Energy Institute (NEI) provided to the NRC survey results regarding licensees' capabilities to perform multi-unit dose assessments, implementation time frames to obtain multi-unit dose assessment capability, and compensatory measures for the interim period (Reference 2). In Reference (3), the NRC requested further detailed information regarding the current and the anticipated capabilities of sites to perform multi-unit dose assessment. NEI informed the NRC in Reference (4) that the industry had elected to provide the requested details directly to the NRC staff.
The enclosure to this letter includes the requested information for NextEra Energy Point Beach, LLC. The enclosure includes a discussion of the current capability to perform multi-unit/multi-source dose assessments, the interim compensatory measures for this capability, and the final permanent solution.

ENCLOSURE 1 NEXTERA ENERGY POINT BEACH, LLC POINT BEACH NUCLEAR PLANT IMPLEMENTATION OF MULTI-UNIT/MULTI-SOURCE DOSE ASSESSMNET CAPABILITY 1.0 Introduction The NRC Fukushima Near-Term Task Force (NTTF) Report (Reference 1) dated July 12, 2011, discussed the gap in capability for US commercial nuclear power plants to perform multi-unit dose assessments. In January 2013, the Nuclear Energy Institute (NEI) sent a letter to the NRC (Reference 2) that reported survey results regarding licensees' current capabilities to perform multi-unit dose assessments. The NEI letter also discussed licensees' expected implementation time frames and compensatory measures for the interim period. In Reference 3, the NRC requested further detailed information regarding the current and anticipated capabilities of sites to perform multi-unit dose assessments. NEI informed the NRC in Reference 4 that the industry had elected to provide the requested details directly to the NRC staff. The requested details were to include:
A summary of the current capability to perform multi-unit/multi-source dose assessment, The anticipated schedule to establish the capability on an interim and/or permanent
- basis, Due dates associated with each key schedule action or milestone, A description of how the implementation schedule will be tracked.
2.0 Summary of Current Multi-Unit/Multi-Source Capability Manual Dose Assessment Capability-A Point Beach Nuclear Plant (PBNP)
Emergency Preparedness Procedure provides guidance for combining release information from multiple sources to perform an offsite dose assessment. In addition, another PBNP Emergency Preparedness Procedure provides guidance for calculating projected Whole Body Dose (TEDE) and Thyroid dose (CDE) at the site boundary.
Meteorological information is available from onsite and the nearby National Weather Service Offices. It should be noted that this method would remain functional for an extended loss of AC scenario where power to plant components (fans, dampers, monitors, etc.) would not necessarily be operational.
3.0 Interim Measures Based on the evaluation discussed in Section 2.0 above, PBNP has no interim actions required.
4.0 Permanent Solution Based on the evaluation discussed in Section 2.0 above, PBNP has no additional required actions.

5.0 Schedule Based on the evaluation discussed in Section 2.0 above, PBNP has no additional required actions.
