Time intervals were inserted to the definitions for use in establishing lj surveillance frequencies Section 3.0, page 9:

d-Shutdown margin with all' rods inserted was changed to 0.025 delta K/K 94 and with the most reactive rod stuck. out to 0.0045 delta K/K in order ij-i to allow us to meet shutdown margin requirements with the maximum excess j

reactivity of 0.038 delta K/K loaded in the core.
