Neutron monitoring solutions

Information and control for power and safety management in large and next generation reactors

Ultra Energy neutron monitoring solutions ensure safe long-term nuclear power generation

  • ‘Core to control room’ solutions provide actionable information to operators
  • Full power range of reactors, from start to full power
  • High temperature detectors support advanced reactor designs

Ultra Energy designs and manufactures neutron monitoring solutions that ensure safe power generation by reactors over the full life of a nuclear power plant. Our ‘core to control room’ solutions detect the presence of neutrons and provide actionable information to human operators, as well as integrating with automated safety control and shutdown systems.

Custom solutions for new or existing reactor designs

Operators must know the neutron flux in a reactor core to make informed safety and control decisions. As well as supplying custom solutions for new reactors or replacements for existing designs, we help developers construct a safety case for neutron monitoring systems. Ultra Energy’s neutron detectors cover the full power range of the core and now work at up to 800o Celsius, which is of significant value to designers of advanced reactors.

Embedded across the nuclear power fleets and supporting development reactors

Ultra Energy owns the neutron detector design for the UK’s AGR and has manufactured replacement detectors for these sites for the last ten years, having supported EDF’s safety-case justification for their life extension with the UK regulator. As well as supplying neutron monitoring solutions to these and other civil nuclear programmes, we also support research and development reactors and supply the British Royal Navy’s fleet of nuclear-powered vessels.
