Indian Point Implementation of Multi-source Dose Assessment Capability Indian Point Unit Numbers 2 and 3 Docket Nos. 50-247 and 50-286 License Nos. DPR-26 and DPR-64 NEI letter, J. E. Pollock to J. T. Wiggins (NRC); "Commitment for Implementation of Multi-Unit Dose Assessment Capability," dated March 14, 2013 (ML13073A522)
Dear Sir or Madam:
This letter provides information regarding multi-source dose assessment capability for Indian Point Energy Center (IPEC) in response to the referenced communication from the Nuclear Energy Institute (NEI).
The Emergency Response Organization at IPEC currently uses the MIDAS (Meteorological Information and Data Acquisition System) computer program for modeling offsite dose assessments. This computer program is used to estimate the dose consequences in the emergency response sectors for input parameters (source term, meteorological conditions, etc.) based on a single release point. In the event of a scenario with concurrent releases from more than one release point, separate dose analysis runs can be performed with MIDAS using the applicable data inputs for each release point. The results of the separate dose consequence analyses can be combined to obtain the total dose consequence.
Instructions for performing this type of analysis are provided in the dose assessment emergency response procedure.
Consistent with the referenced letter, IPEC plans to transition to software such as Unified Rascal Interface (URI) Version 2, which provides for an improved capability for multi-source dose consequence analysis. This transition is identified as a regulatory commitment with a completion date of not later than December 31, 2014.

Sincerely, JAV/sp
