Pikckering, J. L.

In the prestressed concrete reactor vessel (PCRV), cooling tubes are welded on the concrete side of the cavity liners. These cooling tubes are placed at pitches determined by the design temperature limits of the liner/concrete interface and are subject to shear loading resulting from prestressing, pressurization, temperature, and creep of the PCRV. This test program consists of both monotonic and cyclic testing of models simulating prototype cooling tube/concrete assemblies. The Phase III tests determined the stiffness characteristics and failure modes of four possible cooling tube configurations having round and square cross sections. A comparison with the previously obtained results of the Phase I and Phase II tests on 1-in. x 1-in. square tubes is also included.
