To ask the Secretary of State for Energy whether he will now make public the plans proposed, during the chairmanship of the Atomic Energy Authority of Sir John Hill, for the decommissioning of nuclear power stations by removing most parts, other than the reactor concrete shields, and smothering the site with landscaped turf and earth; and what were the cost estimates at (a) plan prices and (b) current prices.

I regret that my Department is unaware of the particular plans referred to by the hon. Member, and that, on the basis of the information he has provided on the question, further research could be carried out only at disproportionate cost.
