Decommissioning Windscale Advanced Gas-Cooled Reactor

Proceedings of the Institution of Mechanical Engineers Part A Power and Process Engineering (1985)

H. Lawton

This paper describes the UKAEA project to decommission the Windscale advanced gas-cooled reactor. The plan is to take down the reactor itself, the heat exchangers and the sphere in which they are all contained. A special remote-handling machine is being developed which will cut up the radioactive items, and a facility is being built to package the waste for storage and disposal.

Irradiation testing in fast reactors in the United Kingdom

OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) (1970)

H. Lawton I.R. Birss K.Q. Bagley

The criteria established for the successful use of DFR for irradiation purposes and the advantages of using a fast reactor are discussed. Examples are drawn from the PFR program for testing fuel, cladding, pins and assemblies, and from tests in support of thermal systems under development. Lack of instrumentation in the experimental rigs results in particular importance being placed on post-irradiation examination and on interpretation of the data. One advantage of DFR is that experiments may be examined non-destructively and returned to the reactor for further irradiation. An indication is given of the proposed use of PFR for experimental purposes, of how this will differ from the current use of DFR, and of its capabilities. (UK)
