,g;3; l (BAST) indicated the boric acid concentration was below the specification limit of l g l 20,100 PPM boron. Because the reactor cavity was filled, the Refueling Water l l o ,3 y l Storage Tank (RWST) was below the minimum specification level limit. At o720 hours, l l 0 l6 l l Nos. 11 and 12 BAST's were declared inoperable, resulting in no borated water l .
