Description

Plutonium-240 is a synthetic, fissile isotope of plutonium, identified by CAS NO 14119-33-6. This material is of critical importance in specialized nuclear applications due to its specific neutron emission properties and its role as a component in mixed-oxide fuels. It is primarily required by advanced research institutions, national laboratories, and entities involved in nuclear energy and defense sectors for use in reactor physics studies, neutron source fabrication, and isotopic analysis.

Application

• Primary component in mixed-oxide (MOX) nuclear fuels for power generation.
• Calibration and reference standard in mass spectrometry and radiochemical analysis.
• Neutron source for reactor start-up, physics experiments, and non-destructive testing.
• Critical material in nuclear weapons research and stockpile stewardship programs.
• Target material for the production of other transuranic elements in particle accelerators.
• Research applications in the study of nuclear fission properties and decay heat.

Quality Control

All Plutonium-240 materials are produced and handled under the strictest quality protocols, adhering to national and international nuclear material control standards. Isotopic and chemical purity are verified through advanced analytical techniques including alpha spectrometry, mass spectrometry, and gamma spectroscopy. A comprehensive Certificate of Analysis (COA) detailing isotopic composition, radioactive concentration, and impurity profiles is provided with each shipment to ensure traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric and radioactive nature, material must be stored under an inert atmosphere (e.g., argon or helium) in a certified, shielded containment vessel designed for α-emitting nuclides. Storage must be in a dedicated, secure, and ventilated facility with strict access controls and continuous monitoring for contamination, in full compliance with national nuclear regulatory authority requirements.
