Beck, R G

An experimental study of the hydraulics of fixtures used to hold capsules for irradiation in the ETR was made in an out-of-pile hydraulic test facility. The results are presented to supplement a report giving methods of calculating coolant flow through experiments in the ETR or MTR (Ref. IDO-l6368). Test results indicate that calculated flow rates through experiments in the ETR or MTR are usually about 15 to 30% different than measured flow rates. Capsule experiments are loaded into thin-walled aluminum tubes designed for irradiation in holes provided in the MTR and ETR core and reflector. Several different types of tubes are used to hold the capsules, which usually have outside diameters of 5/ 8 inch, 1 1/8 inch, or l inch. These tubes are called S-baskets, X-baskets, SB- baskets, and B-baskets. Results obtained with baskets full of solid capsules for conditions corresponding to ETR operation with a core pressure differential of 55 psi, and MTR operation with a core pressure differential of 40 psi are tabulated.
