SNM-1107 1.8.1.3 (Continued) d is greater than the solubility limit for uranium in solutions.
In addition, the average volume occupied by the rings in the existing tanks is approximately 39 volume %.
The use of any other nuclear poisons or any use of poisons for primary criticality control requires a specific license amendment.
1.8.1.4 Nuclear. Interaction Evaluations, Af1 subcrits must meet the MPV's and must have a separation of at least one foot edge-to-edge between i
any two subcrits.
l; i
Interaction between subcrits which are not isoleted (12.1.1) is evaluated using one or more of three methods:
(1) surf, ace density, (2) solid angle and l
(3) KENO-II Monte Carlo computer code. The 1
surface density method requires that each suberit be limited to the nuclear equivalent of a sphere having 1 3 times the volume of an unreflected 0
critical sphere of the same material (1 3 " fraction 0
critical").
Values are established for each control
