EGCR CORE STRUCTURAL ANALYSIS. THE EFFECTS OF FAST-NEUTRON IRRADIATION AND THE BOWING CHARACTERISTICS OF THE GRAPHITE COLUMNS

PDF Version Also Available for Download.

Description

An analysis of the EGCR core structure was made to determine the lateral deflections (bowing) of the graphite columns resulting from shrinkage caused by fast-neutron irradiation, the life expectancy of each column due to restraints imposed on the bowing, and the reaction forces induced in the supporting structures. Based on currently avallable data for EGCR type graphite shrinkage and assuming experimental loop operation, a maximum bowing potential of 3.61 in. was calculated for an interior column. It was found that strains equivalent to the rupture strains observed from tensile tests could be expected after 4 to 6 years of full-power ... continued below

Over half of the columns will reach these strains before the 20-yr reactor design life is reached. (auth)
