Neutron Shielding Device and System with a Neutron Source and a Neutron Shielding Device

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a neutron shielding device consisting of a steel plate covered by a layer made from a material with much higher thermal conductivity (such as aluminum), which contains internal cooling channels. These channels allow coolant to flow through, effectively transferring heat away from the shield and preventing overheating. The device is particularly robust and combines efficient neutron blocking (from the steel) with improved heat dissipation (from the conductive layer and cooling channels).

Use CasesContent extracted from patent full text and abstract with AI.

• Neutron shielding for research or power nuclear reactors to protect components and personnel from neutron radiation.
• Integration into facilities with spallation neutron sources, such as the European Spallation Source (ESS).
• Protection of sensitive equipment in particle accelerators or fusion reactors.
• Shielding for radioactive laboratories or transport containers involving neutron-emitting materials.
• Improved thermal management of neutron moderators and reflectors in experimental physics setups.

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced heat dissipation compared to traditional all-steel neutron shields, reducing the risk of overheating and mechanical failure.
• Maintains a high level of neutron shielding effectiveness due to steel core.
• Increased structural stability under thermal stress, thanks to improved material layering and bonding techniques.
• Customizable cooling channel design allows for efficient tuning to operational requirements and heat loads.
• Potential for lighter and more compact shielding assemblies without sacrificing performance.
