§ Mr. Alisonasked the Minister of Power what proportion of the total output of pulverised fuel ash from all coal-burning power stations was disposed of commercially for construction or other projects in 1968; and what proportion of such ash it is hoped to dispose of in this way from the Drax power station, when in operation.
§ Mr. FreesonThe latest figures available are for the year ended 31st March, 1968, during which 3.7 million tons of pulverised fuel ash representing 42 per cent. of the total output was sold (see paragraph 51 of the Central Electricity Generating Board Annual Report 1967–68).
The Board forecasts sales of about 4 million tons of ash from Drax power station over the 30-year life of the station. It estimates total ash output over that period to be 32 million tons from a 4,000 MW station or 16 million 136W tons from a 2,000 MW station. It is not possible to give an estimated annual breakdown.
