Construction Permit Application Review SHINE Medical Technologies Safety Panel 2 December 15, 2015 NRC-012-R
Panelists
- Project Manager, NRR
- Senior Reactor Systems Engineer, RES
- Kevin Morrissey
- Project Manager, NMSS 2
Review Methodology
- Two methodologies applied to SHINE accident analyses
- Maximum hypothetical accident
- Integrated safety analysis
- Radiological and chemical hazards evaluated against 10 CFR Parts 20 and 70, respectively 3
Irradiation Facility Accident Analysis
- Irradiation facility characteristics:
- Operates at low power, pressure, and temperature
- Large heat sink for passive decay heat removal
- Radiological sources 4
Event Identification
- Delineation of possible accident categories
- Identification of limiting accident for the category
- Strategy to mitigate accident and limit consequences
- Analysis of dose consequences 5
Safety Concept
- Detection of high radiation levels
- Confinement of radiation source
- Evacuate workers
- Filter releases to environment
- Emergency planning zone could be the operational boundary 6
Limiting Accident
- Release of irradiated target solution from one TSV
- Consequences bounded by RPF maximum hypothetical accident
- Meets 10 CFR Part 20 limits
- 5 rem for workers
- 100 mrem for public 7
Production Facility Accident Analysis
- Radiological and chemical accident analysis performed
- Defines facility hazards and controls that support establishment of design basis 8
Production Facility Accident Analysis
- Multiple event types:
- Radiological accidents
- Chemical accidents
- Criticality accidents
- Fires
- External events 9
