The Rajasthan Atomic Power Project has two nuclear power reactors, heavy water moderated and cooled and with uranium oxide fuel. The experience in the construction of buildings and structures for the twin units of 200 MW(e) each of RAPP is described. The civil engineering aspects of the reactor construction are highlighted as the construction period for major civil works takes about4O to 50% of the project construction time. Suggestions regarding the improvements in the construction methods to achieve the desired reduction in construction time are made. The reactor building of RAPP consists of (i) containment shell comprised of a cylindrical R. C. shell of 39.624 m diameter capped by a hemispherical prestressed concrete shell, (ii) calandria vault in heavy concrete which houses the reactor core, and (iii) internal slabs and walls supported on structural steel framework. Functional requirements of reactor building construction and the major criteria, such as structural integrity, leak tightness, voids in concrete, uniformly high quality construction, construction in planned sequence to utilize stage by stage the portions built, etc., are discussed.
