Physics of gas cooled reactors
From meeting on new developments in reactor physics and shieiding calculations; Lake Kiamesha, New York, USA (12 Sep The temperature coefficient of the HTOR is composed of a strong negative Doppler coefficient and a positive moderator coefficient, the net effect being about -10 x 10/sup -5// deg C at operating temperature. the positive moderator coefficient is a result of the absence of significant density coefficients and the nuclear characteristics of U- 233. In addition, selected iission products, principally Xe-135, contribute positive components to the temperature coefficient. Current estimates of the value of the temperature coefficient in the HTGR are presented along with recent experimental data pertinent to the subject. (11 references) (auth)
