Something has happened with nuclear, there is about 1.5GW missing compared with a few weeks ago.

The present output is fairly average, a few weeks ago was unusually good.

Various outages at present, one reactor shut down for repairs to steam turbine overspeed protection, another planned outage extended for boiler tube leaks, and one shut down due to defective boiler feed pump.

One reactor reducing load prior to statutory shutdown for inspection of the core and another running at about one third capacity due to refueling.

Between 6 and 7GW is a fairly typical winter output, much more than that is a most useful bonus but should not be counted on.

UK nuclear output is down to about 6.5GW at present.

Three reactors are shut down on a planned basis for statutory inspections and should return to service before the peak demand season.
Two reactors are operating at significantly reduced load for refuelling, and again should return to full load operation before peak demand season.

Of slightly greater concern is the position at Heysham 1.
One reactor has been operating on 7 boilers out of 8 for a couple of years due to a fault.
I now observe that the other reactor is at significantly reduced load due to a boiler tube leak.
Makes one wonder if boiler leaks are going to be a regularly recurring cause of shutdowns or reduced output.
