摘要

PPROBLEM TO BE SOLVED: To provide an inspection method for simply finding the breakage rate of a ZrC layer so far hard to find, as to coated fuel particles for a high-temperature gas reactor with the ZrC layer formed as a third coating layer. PSOLUTION: This ZrC layer breakage rate inspection method on the coated fuel particles for a high-temperature gas reactor is equipped with: a process for press-forming or mold-forming a plurality of coated fuel particles together with a parent material comprising graphite material into prescribed shapes, then baking them into a fuel compact or pebbles, heating the fuel compact or pebbles in a hydrogen atmosphere to vaporize carbon content, thereby acquiring particles under test with the third coating layer exposed; a process for boiling the particles under test in nitric acid liquid for a previously determined time period; and a process for determining the quantity of uranium having transuded in the acid liquid by a chemical analysis method after the boiling process.

要解决的问题：提供一种检查方法，以简单地找到迄今难以找到的ZrC层的破损率，以ZrC层作为第三层涂层的高温气体反应器的涂覆燃料颗粒层。

解决方案：该用于高温气体反应器的涂覆燃料颗粒的ZrC层破损率检查方法配备：用于将多个涂覆燃料颗粒与母体材料一起压制成型或模制的工艺，包括将石墨材料制成规定的形状，然后将其烘烤成燃料块或小卵石，在氢气氛围中加热燃料块或小卵石以蒸发碳含量，从而获得暴露出第三涂层的被测颗粒;在预先确定的时间段内将被测颗粒在硝酸液体中煮沸的过程;沸腾后，通过化学分析法求出渗入酸液中的铀量的方法。
