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 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 sumrnary 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 Seabrook Station's dose assessment model, RADDOSE V is capable of multi source dose assessment.
In addition to calculating dose from the installed plant effluent release paths, RADDOSE V provides the capability of calculating the source term from a grab isotopic sample, field team monitoring data (for Unmonitored release), or direct input of a release rate. The model provides for up to 5 release paths per time step.Dose assessment input data is available both manually and automatically from the plant process computer.
The dose assessment software is located on multiple computers and in the absence of a plant data feed, manual input can be used.3.0 Interim Measures Based on the evaluation discussed in Section 2.0 above, no interim actions are required for Seabrook Station.
4.0 Permanent
Solution Based on the evaluation discussed in Section 2.0 above, no interim actions are required for Seabrook Station.5.0 Schedule Based on the evaluation discussed in Section 2.0 above, no interim actions are required for Seabrook Station.6.0 References
