A Comparison of Human Error Probabilities Collected from HuREX and SHEEP Frameworks

This paper discusses how different are the HEPs collected from HuREX and SHEEP frameworks. This study is a preceding research to infer full-scope HRA data based on the data collected from the SHEEP framework. For the comparison, we used HEPs in the HuREX database published in KAERI-TR-6649 [6]. The HEPs have been collected from actual licensed operators when manipulating MCR simulators of Westinghouse type and Optimized Power Reactor (OPR1000) type in South Korea. For the HEPs based on the SHEEP framework, these have been collected from actual licensed operators and students when using a simplified simulator, i.e., Rancor Microworld.

Aircrew, Cancer and Probability of Causation - Paper 60

Aircrew are radiation workers who normally are not provided with dosimetry. The Energy Employees Occupational Illness Compensation Policy Act (EEOICPA) established an important legal precedent that fundamentally changed employer liability for companies that expose workers to radiation. We have applied the method used by EEOICPA (Interactive Radio Epidemiological Program (IREP)) to cancers found in excess in published epidemiological studies of aircrew. Our results show that from 4 to 8 of the 12 cancers reported in the literature in typical aircrew may be compensable using EEOICPA methods. The other cancers may be compensable as well, given an unusual flight career with greater exposures than typical. Our research demonstrates there are cancers that have a 50% POC at annual exposures within the range of those asserted by the FAA for aircrew. The FAA currently estimates aircrew annual exposure as up to 6 mSv from GCR alone. While dosimetry is urgently needed for existing aircrew, historical dose reconstructions will be needed to address POC for aircrew diagnosed with a radiogenic cancer. (authors)
