Effects of High Temperature Neutron Irradiation on Dimension and Thermal Expansion Coefficient of Nuclear Grade Graphites

Abstract: This paper describes the experimental results and discussions on the changes in dimension, volume and thermal expansion coefficient of five nuclear grade graphites which were made from petroleum coke or gilsonite coke and irradiated in the JMTR a t 670--1,26O0C UP to the maximum neutron fluence 3.3 x lo2' n/cm2 (E>0.18 MeV).Dimensional or volume shrinkages for all samples were observed after irradiation and their changes depended on the kind of graphite studied. T h e changes in thermal expansion coefficient w… Show more

“…Newer data from the INNOGRAPH/ARCHER irradiation program has been investigating the dimensional changes that occur in multiple iso-molded grades (grade is not reported) [35]. The 600°C and 750°C low-fluence IG-110 results from Matsuo et al [32,34], and the 750°C results from INNOGRAPH/ARCHER [35] irradiations agree well with the G347A volume change for the high temperature regimes. The agreement of the results from this work and measurements on other grades is shown in Figure 16.…”

“…Little data is available regarding the neutron irradiation-induced changes in other fine-grained nuclear graphite grades. The only fine-grained grade that has been studied to fluences that are similar to this work is IG-110 [15,[32][33][34]. The earliest research was performed on IG-11, the non-purified precursor grade to IG-110 [33], and was shortly followed by an investigation of IG-110 [32,34].…”
