摘要

美国能源部(DOE)目前正准备向美国核管理委员会提交一份申请,要求批准建设一个监测地质储存库。该储存库将把乏核燃料(SNF)和国防高放射性废物(DHLW)装在废物包装中,放置在地下隧道或漂流堆中。本文的主要目的是对在炮位漂移中受破坏性火成岩侵入事件影响的含有DOE SNF的废包进行临界分析。废物包装的特点是一个DOE SNF罐放在中心,周围是五个高放废物(HLW)玻璃罐。有效中子增殖因子(k{sub eff})在侵入火成岩事件期间和之后确定了废物包的潜在配置。由于火成岩侵入后潜在情况的复杂性,寻找关于临界的保守和边界配置需要一些额外的考虑。特别是,必须检查塌陷和损坏的废弃包装的几何形状,必须在一系列参数上模拟漂移条件,并且必须考虑DOE SNF和废弃包装材料的化学降解,以应对预期的高温。这种计算的第二个目的是提供一种更简单的方法来选择保守和边界构型,以适应广泛的结束条件。«少

Criticality Potential of Waste Packages Containing DOE SNF Affected by Igneous Intrusion
The Department of Energy (DOE) is currently preparing an application to submit to the U.S. Nuclear Regulatory Commission for a construction authorization for a monitored geologic repository. The repository will contain spent nuclear fuel (SNF) and defense high-level waste (DHLW) in waste packages placed in underground tunnels, or drifts. The primary objective of this paper is to perform a criticality analysis for waste packages containing DOE SNF affected by a disruptive igneous intrusion event in the emplacement drifts. The waste packages feature one DOE SNF canister placed in the center and surrounded by five High-Level Waste (HLW) glass canisters. The effective neutron multiplication factor (k{sub eff}) is determined for potential configurations of the waste package during and after an intrusive igneous event. Due to the complexity of the potential scenarios following an igneous intrusion, finding conservative and bounding configurations with respect to criticality requires some additional considerations. In particular, the geometry of a slumped and damaged waste package must be examined, drift conditions must be modeled over a range of parameters, and the chemical degradation of DOE SNF and waste package materials must be considered for the expected high temperatures. The secondary intent of this calculation is to present amore » method for selecting conservative and bounding configurations for a wide range of end conditions.« less
