Irradiation behavior of coated fuel particles, (5). Irradiation by JMTR 73F-13A capsule. Fukuda, Kousaku; Kashimura, Satoru; Ogawa, Toru; Minato, Kazuo; Ikawa, Katsuichi; Iwamoto, Kazumi; Ishimoto, Kiyoshi (Tokai Res. Establ., Japan At. Energy Res. Inst., Tokai, Japan). Report, JAERI-M-83-232, 74 pp. Avail. INIS From: INIS Atomindex 1985, 16(7), Abstr. No. (Japanese) 1984. DOCUMENT TYPE: Report CA Section: 71 (Nuclear Technology) The TRISO coated fuel particles prepd. correspondingly to VHTR preliminary design in FY1974, the coated particles imported from England which were prepd. also under VHTR design, the coated particles for 1st OGL-1 fuel assembly, and ZrC [12070-14-3] coated particles were irradiated in the fuel zone of JMTR 73F-13A capsule. Irradn. of these coated particles was attained up to 3 ′ 1021 n/cm2 of fast n fluence, up to 5.3% FIMA of burnup, and up to 1630° of temp. (peak temp. 1730°). In the post-irradn. examn., inspection of surface appearance of the coated particles, x-ray microradiog., ceramog., acid-leaching expt., measurements on fission product inventory in the coated particles and on the fractional releases of metallic fission products, EPMA(XMA) observation on segregation of the metallic fission products in the coated particles, and measurement on crushing strength of the irradiated coated particles were made. In PIE, the coated particles prepd. in FY1974 were intact by irradn. up to 2.7 ′ 1021 n/cm2 of the fast n fluence, 4% FIMA of burnup and 1380° of max. temp. Both of the domestic coated particles and the imported particles kept their integrities under irradn. below 1380°. Above 1600°, the domestic particles did not fail as much as the imported ones.

Sintering at high pressures gave a denser product than sintering in vacuum or protective atm. The binders had little effect on the elec. properties of ZrC, which is useful for magnetohydrodynamic ele. generators. Protective coatings or atms. were necessary.
