An account is given of the maintenance and remedial work which has been done within the biological shield of the Windscale reactors, and covers: (a) Retention of reactor fuel elements which were tending to blow out of the graphite channels. (b) Remote welding and cutting operations using oxy-acetylene equipment at distances of up to 20 feet from the operating position. (c) Repair work on the fuel element detection gear which involved the entry of personnel into the biological shield. Details are given of the health physics control and of radiation exposures received by personnel during the maintenance of the fuel element detection gear. No maintenance work has been necessary within the biological shields on Calder Hall Reactors, but both heat exchangers and gas inlet ducts have been entered for inspection. The result of such inspections and health physics data are given. (auth)
