Book Description
A Cryogenic Irradiation Facility (CRIF) has been designed, fabricated, and tested for use in the pool of the Ohio State University Research Reactor (OSURR). This CRIF will support in situ radiation induced damage experiments in optical and electronic materials from cryogenic temperatures and temperature controlled low temperature annealing experiments from cryogenic temperatures to above room temperature. The facility has been tested with liquid nitrogen and liquid helium out of the reactor pool. Temperature control has been demonstrated in the experimental volume of the CRIF from 4.2 K to above room temperature. The 10" Dry Tube, which will house the CRIF in the OSURR pool, has been inserted into OSURR pool and tested. The empty 10" Dry Tube and the CRIF have been simulated in a model of the OSURR using MCNP6 to understand the predicted radiation fields and total energy deposition in the empty 10" Dry Tube and in typical optical and electronic materials in the experimental volume of the CRIF. The radiation fields and the total radiation energy deposition have been used to predict experimental operating parameters for future CRIF experiments, based upon desired dose calculations and time to boil-off for the liquid helium inside the CRIF.

Book Description
Design analysis studies have been made for various in-core irradiation facility designs which are presently used, or proposed for future use in the MITR-II. The information obtained includes reactivity effects, core flux and power distributions, and estimates of the safety limits and limiting conditions for operation. A finite-difference, diffusion theory computer code was employed in two and three dimensions, and with three and fifteen group energy schemes. The facilities investigated include the single-element molybdenum sample holder, a proposed double-element irradiation facility and a proposed central irradiation facility design encompassing most of the area of the three central core positions. In addition, a comparison of the effects of various absorber materials has been made for a core configuration which includes three solid dummies. Flux levels in the molybdenum holder facility and in the beam ports were calculated for both three and five dummy cores. Flooding the sample tube in these cases was found to increase the safety and operating limits, but not to unacceptable levels for an 8 inch blade height. For the five dummy case, the operating limit in the C-ring was predicted to reach its maximum allowed value at a blade bank height of 13.6 inches. The reactivity effect of flooding was calculated to be 0.19%AK for the five dummy case, in direct agreement with the measured value. Flooging the large sample channel in the double element facility was found to increase the reactivity by 1.5 6%AK ff and also to cause an unacceptable power-peaking. The proposed central irradiation facility is a thermal flux-trap which could produce thermal flux values of up to 2.0 x 1014 n/cm 2 sec. Computer estimates show that flooding this facility's central sample tube would increase this value to 2.5 x 1014 n/cm2 sec, without resulting in an unacceptable power peak.
