SUBJECT:
Response to Questions Raised by Bob Carter
=
Dear Ted:
m-
-f This letter will confirm my responses,in a telephone conversation with Bob Carter on January 24,1990, to verbal questions that had been raised relative to certain aspects of; Manhattan College procedure " Experiments for Reactor Power Level Determination" sent to you in our letter of. December 12,1989 _ The responses were:
- Method 11 described in the " Experiment" will be the primary approach used to determine
- the reactor' power level. We will revise the physics in method I and use it'as a-backup-procedure.
f
- The core parameters will be experimentally redetermined when the new core is loaded into the reactor,
- inumcthod ll.) the ratios -
0.695 and k-1.20f were extracted from 'the data
~
]c'ollected during the initial," Critical ~and Subcritical Reactor Experiments" run af tcr installation'of the reactor in~ the 1960's. Thes_c values will be' properly redetermined -
~
.during the experiments to be run-upon installation of the new core.
-.* The value 3.54 x 10'" used in equation 2 had been empirically arrived at.,This value will now be independently determined from the parameters of the fission process for use in the calculation of reactor power.
i Sincerely, y
