Specialty chemicals for the nuclear power and energy sector
MRX supplies specialty chemicals for the nuclear power and energy sector, covering reactor coolant chemistry, radiation shielding materials, decontamination agents, and neutron absorber compounds.
Our product range supports pressurised water reactor (PWR) operations, facility maintenance, decommissioning, and radiation protection.
All products are freely tradeable industrial chemicals supplied to applicable ASTM, ASME, and nuclear industry quality standards.
Reactor Coolant and Water Chemistry
Pressurised water reactors require precise chemical control of both primary and secondary coolant circuits. Boric acid serves as a soluble neutron poison to regulate reactivity throughout the fuel cycle, while amines maintain optimal pH to minimise corrosion. Chemical Function Specificatio

Neutron Absorber Materials
Neutron absorbers are used in control rods, burnable poison fuel assemblies, and spent fuel storage racks to manage criticality. Boron carbide and gadolinium compounds are the two principal absorber families in commercial reactor service. Chemical Function Specification

Radiation Protection Materials
Radiation shielding protects personnel and equipment from gamma and neutron radiation during reactor operation, maintenance, and decommissioning. These materials are incorporated into permanent structures, temporary barriers, and transport containers.

Decontamination Chemicals
Nuclear facility decontamination removes radioactive contamination from metal surfaces, piping, and equipment. Chemical decontamination processes use sequential oxidising and reducing treatments to dissolve activated oxide layers and chelate radionuclides for removal.
