目的考察并验证旧折叠式碘吸附器换炭再用的可行性。方法采用使用过的碘吸附器和“模拟使用过的碘吸附器”壳体进行两组换炭再用试验。结果被试验碘吸附器净化系数和阻力均满足核电站规定的技术指标的要求。结论使用过的折叠式碘吸附器壳体至少可以换炭再用三次以上,其性能良好。 Objective To investigate and verify the feasibility of reusing old folded iodine adsorbers. The method uses both the used iodine adsorber and the “simulated used iodine adsorber” housing for two sets of re-use tests. Results The adsorption coefficient and resistance of iodine adsorbents tested all met the technical specifications of nuclear power plants. Conclusion The folded iodine adsorber housing can be reused more than three times for better performance.
