Abstract
A storage tank for radioactive fissile material solutions. The tank comprises at least one cell containing a radioactive solution and a solid neutron-absorbing material while preventing any risk of criticality. A network of substantially vertical tubes is arranged within said cell and metal walls completely separate the radioactive solution from the solid neutron absorbing material. Said tubes contain the neutron absorbing material and are located in compartments defined by the metal walls throughout the radioactive solution. Said tank occupies a reduced floor space.
Claims7
A storage tank for radioactive fissile material solutions, said tank (11) comprising at least one cell for containing a radioactive solution (12) and solid neutron absorbing material (14) for avoiding the risks of criticality, said radioactive solution (12) being separated from said solid neutron absorbing material (14) by metal walls (12', 13'), which tank is characterized in that an array of substantially vertical tubes (13) containing solid neutron absorbing material (14) is arranged within said cell, said tubes (13) having metal walls (13') and being located in compartments which are themselves delimited by metal walls (12') and distributed throughout said radioactive solution (12).
