STARTUP TEST-N-l - PROCEDURES N-REACTOR STARTUP PHYSICS TEST PROGRAM HOT LATTICE TEST & INSTRUMENTATION CALIBRATION

摘要

The pile has already been loaded to full size, therefore, the operational hazards analyses will apply insofar as control system strengths and rod with¬drawal reactivity ramps are affected. However, the hot test produces the narrowest total control shutdown margin for the rod system under accidental cold water dump conditions now described for N-Reactor. This margin might limit the peak temperature at which this test may be run. At the time the test is begun, the control system strengths will be known from the previous calibrations, thus establishing the maximum temperature allowed,
