Abstract

Hinkley Point 'A' Nuclear Power Station historically experienced a decline in electrical generation capability of about 30 MWe. This paper describes the identification of the cause of this deterioration as a thin porous carbonaceous deposit on the gas side of the boiler tubes. The theoretical and experimental investigations which showed that this deposit had an effective thermal conductivity of about 0.05 W/m/K are described.

Current progress with deposit removal is presented showing that a substantial improvement in boiler performance has been achieved. This has increased station output by about 20 MWe, thus significantly helping to restore electrical generation capability to historic levels.
