HC Deb 18 March 1968 vol 761 c2W
21. Mr. Wall

asked the Minister of Technology if he will make a further statement about the development of an economic reactor for nuclear-powered surface vessels.

33. Mr. Ian Lloyd

asked the Minister of Technology what information he has on the actual and estimated operating costs of nuclear-powered surface vessels; and whether he will revise his estimates of the period within which conventional fuels will retain an advantage.

Dr. Bray

A very large power output is required to make nuclear reactors competitive for marine propulsion. A requirement has not yet been found for the combination of speed and size, either for tankers or container ships, which would require this power output. The matter will be kept under review.
