NRC-012 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 (MHA)

- 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 is the site boundary 6

Limiting Accident

  • Release of irradiated solution from one target solution vessel
  • Consequences bounded by production facility MHA

- 5 rem for workers

- 100 millirem for public 7

Production Facility Accident Analysis

  • Radiological and chemical accident analysis performed
  • Defines facility hazards and controls that support design basis 8

Production Facility Accident Analysis

  • Multiple event types considered:

- Radiological accidents

- Chemical accidents

- Criticality accidents

- Fires

- External events 9

Acronyms

  • CFR - Code of Federal Regulations
  • RES - Office of Nuclear Regulatory Research
  • NMSS - Office of Nuclear Material Safety and Safeguards
  • NRR - Office of Nuclear Reactor Regulation 10
