HNPF INPILE POISON RING TEST NO. 2

Technical Report ·
OSTI ID:4085299
Tests were conducted in the Sodium Reactor Experiment (SRE) to obtain temperature and neutron flux measurements that were required for calculating the heat generation rates and thermal conductivity of rare earth oxide control elements that are proposed for use in the Hallam Nuclear Power Facility. The maximum delta T on a horizontal plane between the test assembly and the sodium coolant was 633 deg F. The maximum delta T across an absorber ring was 331 deg F in the eccentric ring while the maximum delta T across an absorber ring wall of the concentrically fixed rings was 271 deg F. Pile gamma heating produced a temperature of 950 deg F on the Zircaloy ring while the sodium coolant was 820 deg F at this level. Results of neutron flux measurements are presented graphically.
