Enclosure for confining radio-active products or waste
First Claim
1. An enclosure for confining radio-active products, comprising in combination:
- a substantially fluid-tight outer rigid supporting shell structure made from reinforced concrete and buried in the ground and opening to the outside through a reinforced concrete chimney-stack;
a first vessel containing said radio-active products which forms a primary barrier and consists of thin corrugated stainless steel sheet material formed with two orthogonally intersecting series of spaced parallel corrugations, a second vessel forming a secondary barrier made from thin corrugated stainless steel sheet material formed with two orthogonally intersecting series of spaced parallel corrugations and which is located between said rigid supporting shell structure and said first vessel;
means for cooling said vessels through fluid flow circulation induced by natural convection within channels adjacent to at least one of said vessels and means for feeding and discharging said radio-active products into and from said first vessel.

Abstract
An enclosure for confining radio-active products or waste comprising a fluid-tight underground rigid supporting outer shell of reinforced concrete opening to the outside through a reinforced concrete chimney, an innermost vessel for containing said radioactive products or waste, surrounded by said shell and made from thin corrugated stainless steel sheet material, an intermediate vessel made from thin corrugated stainless steel sheet material, located between said shell and innermost vessel and surrounding the latter, means for cooling said vessels through fluid flow circulation by natural convection within ducts adjacent to at least one of said vessels and means for feeding and/or discharging said radio-active products or waste into or from said innermost vessel.
