Special incident report power excursion - H Reactor for September 29, 1957
Technical Report
·
OSTI ID:6124357
At 12:51 a.m. on September 29, 1957, a Panellit scram occurred due to a drop in inlet water pressure to tube 1665. Investigation revealed the presence of a ruptured slug and tube in channel 1665, and further checking revealed ruptured slugs also in tubes 1168, 1264, and 2956. These ruptures were caused by operating the center-near region of the reactor at power levels up to 24 per cent above limits for approximately 26 minutes prior to the scram. After removal of the rupture, 250 tubes in the effected region were discharged at 40 per cent of goal concentration to reduce the possibility of additional ruptures during subsequent operation. Completion of rupture removal and the discharge of rupture prone material required 53.6 hours. Operation was resumed at 6:26 a.m. on October 2, 1957.
