ABSTRACT:
A containment casing (10) for a deep well/gravity pressure reactor vessel includes a plurality of casing sections (11) each having a wall portion (20) with corrugations (21). An inner liner (24) and an exterior liner (25) prevent grout material (13) from entering the corrugations (21) during installation. Additionally, inner liner (24) is capable of supporting the hanging weight of the casing sections (11), and yet is susceptible to failure due to stresses induced by thermal fluctuations. The corrugations (21) allow for thermal expansion without a buildup of compression stresses and further allow for angular deviations of the casing (10).
