SPAN 8 QUARTERLY PROGRESS REPORT MAY THROUGH JULY 1964

摘要

The primary loop design point is being modified slightly to assure that the NaK temperature in the boiler does not drop below the mercury boiling tempera ture. The two principal changes are:1) decreasing the NaK AT across the reactor from 200 to 170°F; and 2) decreasing the temperature swing of the reactor coolant outlet temperature. These changes require design modification of the reactor controller, actuator brake, and temperature switch.
