Spent Nuclear Fuel Pools
AR pond – 2003 inspection
An at-reactor pond (AR pond) is located in the reactor hall and serves as an interim spent fuel storage as well as for handling fuel from the reactor core during the reactor outage or under off-load refuelling. The capacity of the AR pond is 60 places for fuel assemblies, 30 of which are held empty for emergency fuel movements from the reactor core.
A reactor annex pond with a total capacity of 100 assemblies is located on reactor sites near the reactor hall.
