HC Deb 23 January 1981 vol 997 c252W
Mr. Cook

asked the Secretary of State for Energy if he will publish in the Offical Report the annual load factor of the Dounreay PFR for the most recent 10 years.

Mr. Norman Lamont

The load factor figures for PFR since it first generated electricity during 1975 are set out in the following table. As stated in the UKAEA's last annual report, despite good performance by the reactor itself, electrical output has been constrained by problems with other parts of the plant and the needs of the experimental programme.

Prototype Fast Reactor Annual Operating Statistics:
Year Percentage of Time Reactor Operational Electrical Load Factor % (i.e. actual electrical output as a percentage of design output)
1975 88.1 8
1976 83.2 20
1977 79.8 29
1978 54.6 33
1979 56.5 27
1980 84.9 21
