Molesworth Airfield (Use) 34. Sir David Renton asked the Secretary of State for Defence what is his policy towards the building of a nuclear power station on the disused airfield at Molesworth, in view of the hazard it would cause to aircraft based at Alcon-bury; and what advice he has given to the Central Electricity Generating Board with regard to this matter. Mr. John A nuclear power station of a design being considered by the CEGI3 would not create a significant hazard to aircraft operating from RAF Alconbury and the board has been so informed. As is customary with developments involving high structures, a recommendation was added to the effect that if the project goes ahead it would be desirable for the cooling towers to be lighted as an aid to aircraft navigation generally.
