Thermal neutron shield and method of manufacture
A thermal neutron shield comprising boron shielding panels with a high percentage of the element Boron. The panel is least 46% Boron by weight which maximizes the effectiveness of the shielding against thermal neutrons. The accompanying method discloses the manufacture of boron shielding panels which includes enriching the pre-cursor mixture with varying grit sizes of Boron Carbide.
1. A thermal neutron shielding material comprising:
a panel containing a resin mixture, said resin mixture including the following constituents: styrene and a polymerization catalyst; and
Boron Carbide, said Boron Carbide being nuclear grade Boron Carbide in particle form and comprises 50% of a first coarse particle size and 50% of a second fine particle size,
wherein said panel is at least 46% Boron by weight.
2. The thermal neutron shielding material of claim 1 wherein said shielding is in a customizable panel form.
3. A neutron shielding structure comprising:
one or more wall elements; and
at least one neutron shielding panel element comprised of styrene and Boron Carbide being secured to said one or more wall elements, said Boron Carbide being nuclear grade Boron Carbide in particle form and comprises essentially 50% of a first coarse particle size and essentially 50% of a second fine particle size,
wherein said neutron shielding panel element is at least 46% Boron by weight.
4. A method of constructing a neutron shielding material comprising:
preparing a mixture including an unsaturated polyester resin in styrene, a curing agent, and nuclear grade Boron Carbide in particle form that comprises essentially 50% of a first coarse particle size and essentially 50% of a second fine particle size;
pouring said mixture; and
curing said mixture so as to obtain a finished panel element,
wherein said finished panel element is at least 46% Boron by weight.
