ANP PROJECT PROGRESS REPORT .. .._ Comparing this with the calculations for the ab sorptions in the CFRMR reflector (this includes beryllium and sodium) operating at CFRMR temperature it can be seen that the absorptions in the SMC are low. By reducing the water volume in the coreof the SMC with aluminum spacers (and thereby reducing the moderation in the core)the absorptions of neutrons in the beryllium can be increased. With 75% aluminum and 25% water in the spaces, the tails of the absorption curves are in good agreement. The shape of the curve for the region near the core-reflector interface does not match as well as the rest of the curve, but it may be lowered by adding the water necessary for cooling and ad- justing the amount of aluminum simulating the sodium. In this manner the curves can be matched throughout. Both curves are normalized to one fission per cubic centimeter in the core region. Power Distribution Some effort has been made to match the power distribution in the core of the CFRMR with that in the SMC for various percentages of water in the core (Fig. 5.4.3). Since a difference between the CFRMR and the SMC with 75% aluminum and 25% water was noted, some effort was made to bring these into better agreement. A slightly different core (100 fuel plates rather than 200) was divided into five regions to determine the variation that 3.6 eEm!?P 2-01-059-760 3.2 - fi 2.8 s il a z 2.4 - P 2.0 I- 0 ONFIGURATION ONFIGURATION ONFIGURATION ONFIGURATION WEEN FUEL PLATES 2 - 4.6 LL I- 4.2 LT w b 0.8 0 a 0.4 0 42 44 46 48 20 22 24 26 SPACE POINTS IN CORE 28 30 32 34 Fig. 5.4.3.

Effect on SMC Power Distribution of Varying the UO, Core. Mass in Five Regions of the Gamma-Ray Sources Another calculation is being carried out at Pratt & Whitney to determine the importance of each region as a gamma-ray source. The reactor is being divided into shells and the gamma-ray intensity from sources in each shell is being determined in a line-of-sight attenuation calculation. This is being done both for the CFRMR and the SMC as a basis of comparison of the two reactors. The remaining region of importance that requires some further work is the heat exchanger. As pre- viously mentioned the source from the circulation of the fuel is not present. Previous LTSF data' indicate that the gamma-ray source resulting from circulation of the fuel contributes approximately 30% of the gamma-ray dose rate outside the reactor shield. It is expected that further analysis of the 'H. Woodsum, ANP Quar. Prog. Rep. March 10, 1956, ORNL-2061, p 237. k *
