NRC-012-R Construction Permit Application Review SHINE Medical Technologies Safety Panel 2 December 15, 2015

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

- 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
