Basically they found an issue in routine maintenance with one boiler

rest down as a precaution so they can inspect them.

If a problem is found them they can operate at reduced output with a single
boiler out of service. It has happened before at one or more of the AGR sites,
but doing so takes some time to remove the boiler, blank it off (gas, steam and
water circuits) and possibly shuffle fuel around the core.
