Radiation Science

The Radiation Science team at AWE holds responsibility for Hardness & Vulnerability activities. The team consists of scientists and engineers with appropriate specialist theoretical knowledge, modelling and experimental competencies.

Neutron Irradiation Services 
AWE has a facility for fast neutron irradiation: This is the ASP Accelerator which has the capability of neutron production at both 3MeV and 14MeV. ASP can provide neutron output in both steady state (DC) and pulsed mode. Pulse lengths range from 5 µSec upwards to near dc operation levels. Maximum neutron output is 2.0E10 n/cm²/sec. ASP is the UK primary 14MeV neutron standard. Current uses for ASP Accelerator include: 

• Fast Neutron Activation Analysis studies:
  ASP has the capability to undertake irradiation of material using a sample rapid transfer system used for sample retrieval where analysis of induced gamma activity is required for short lived radionuclides.
  
• Hardness and Vulnerability testing of components and systems against fast neutron irradiation:
  ASP is used to test discreet components or systems for H&V susceptibility to damage induced by fast neutron irradiation
  
• Calibration of neutron detectors and dosimetry:
  Calibration of neutron monitoring equipment is performed by using techniques specially developed at AWE for accurate dose monitoring.
