THE TEMPERATURE COEFFICIENTS OF NRX AND ZEEP. PART A. TEMPERATURE COEFFICIENTS OF NRX. PART B. TEMPERATURE COEFFICIENT OF A ZEEP LATTICE
Technical Report

OSTI ID:4377323
Results are shown for experimental measurements of the uniform temperature coefficients of the NRX reactor, for both moderator and rod-assembly temperature changes. The agreement of calculated and experimental values of the uniform temperature coefficient is better than the accuracy of the data used in the calculations would warrant. In Part B, experimental measurements of the uniform temperature coefficient of a Zeep lattice are compared with the calculated values. There is good agreement between the calculations and experiment. For lattices of the type described, the leakage terms dominate the contributions to the temperature coefficient. Large corrections are required for changes of radial and vertical extrapolation lengths.
