Temperature Distribution Measurement in the Hot Gas Duct of HENDEL. Results of Tests, No. 1 Cycle and No. 2 Cycle Operations, (February 1982-October 1982)

摘要

The HENDEL (Helium Engineering Demonstration Loop) which was completed on March, 1982, has been operated 3 times so far, including a test operation when it was handed over to JAERI. In the main part of HENDEL which is called a Mother + Adapter (M+A) loop, a hot gas duct through which helium gas of 1000 exp 0 C, 40 atm, 4kg/s flows is installed. This report deals with the measurement and evaluation of temperature distribution of the hot gas duct. The maximum surface temperature of the hot gas duct was 230 exp 0 C, which is low enough, compared with an allowable design temperature of 350 exp 0 C. The effective thermal conductivity of the insulation inside the hot gas duct was found to be 0.40 - 0.49 kcal/mh exp 0 C. (Atomindex citation 15:064804)
