Abstract :
The paper describes the programme carried out to commission and operate the Calder Hall nuclear power station from the time when reactor No. 1 was taken over by the operations branch in May, 1956, until the complete unit was on line at full power. Detail of the methods of carrying out particular aspects of the experimental work is left for other authors; the emphasis in this paper is on the relevance of the tests and their results to the successful operation of the Calder Hall project in particular and the prospects for nuclear generation of power in general. It also indicates the type of work and problem which operation of nuclear power stations will entail.
