, ,  ; gland scaling stear. . The auxiliary boilers had been isolated for a number of months l

, , g due to chemical problems and tube leaks. When the boiler problems were corrected and l

or LER CONTINUATION -- RO# 2-80-3 Facility: 15SEP Unit #2 Event Date 1-3-80 This is the origin of the vessel high conductivity. Scaling steam was swi'ched to reactor steam and the vessel was cleaned up with RWCU. General Plant Opera-ting l'rocedure GP-1 is being revised to ensure that the auxiliary boiler steam lines are sampled before using auxiliary steam.
