HC Deb 23 March 1965 vol 709 c56W
105. Commander Courtney

asked the Minister of Technology if the Vulcain type of reactor incorporating the spectral shift method of control is still considered suitable for installation in a seagoing ship; and to what extent this policy is in accordance with the current views of the technical advisory panel of the working group on marine reactor research.

Mr. Cousins

If a prototype nuclear ship were authorised the choice of reactor would lie between the Vulcain and the Burnable Poison Pressurised Water Reactor.

The Working Group on Marine Reactor Research, having reported in May, 1964, is no longer in being.
