The analysis of the problem PCRV safety leads to a new vessel concept in which the pressure transmitting insulation with its cooling system is outside the hot linear. A control and adjustment system for vessel wall temperature ensures that, under all working conditions, the liner suffers only elastic compression. Outside the thermal insulation (special concrete) a cold steel barrier is placed, which can be constructed as a second liner, so that leaks are limited and can be detected and evacuated. After preliminary development work in the field of high temperature insulating concrete, prestressed concrete technology and instrumentation at elevated temperature, a large experimental ring has been constructed and tested extensively. As part of an experimental high temperature gas loop a large scale model vessel is being built at the Research Center, Seibersdorf, Austria. Construction is nearly complete and a pressure test is scheduled for early 1975. It will be followed by tests under working conditions of PWRs and later of HTGRs. The reference design of such a PCRV with a hot liner for a 1500 MW(e) pressurized water reactor will be finished at the same time as the model vessel.
