Question
You are a member of the professional health physics staff at a nuclear power plant and have been asked to prepare a briefing for management, on occupational radiation exposure in the nuclear power industry. The briefing is to include recent rends in collective doses, means of dose reduction and maintaining doses ALARA, and potential effects of changing regulatory requirements. Your briefing will recognize that, in the United States, collective occupational exposure (person-rem per reactor per year) increased to a maximum in 1980. Since then, the general trend has been down. However, when compared to other countries, the collective dose in the United States is still among the highest, indicating a substantial potential for improvement. In addition to these facts, your briefing will include points covered by the following questions: All of the following factors, with one exception, have contributed significantly to the downward trend in annual occupational exposure per reactor in the United States since 1980. That exception is: Replacement of highly contaminated major components of the reactor system. Completion of NRC-mandated safety actions (such as fire protection, seismic upgrading, etc.). Industry actions including ALARA programs. New plants going into service. Higher capacity factors for U.S. plants.Explanation / Answer
The exception is option a.
Replacement of highly contaminated major components of reactor system.
