Treatment and disposal of waste radioactive ion exchange resins is one of the most urgent problems for nuclear industries in China. Cement solidification technology has many advantages, such as requiring simple equipment, easy scaling-up, low working temperature, no trouble of gas cleaning and low cost. It is a suitable technology for treatment of waste radioactive resins, and has been widely u...

Reliability of Risk Assessments for Geological Disposal of Nuclear Waste

FOR GEOLOGICAL DISPOSAL OF NUCLEAR WASTE Some aspects regarding the reliability of risk assessments for geological disposal of nuclear waste are investigated. The input for the study is given by the opinions of some interviewed Dutch experts and existing literature. The Dutch risk assessment PROSA is used as an example, but the conclusions are seen to be valid more generally. In the PROSA study...

Robotic Inspection of Nuclear Waste Storage Facilities

Introduction Safe disposal of nuclear waste is a difficult problem. Long-term plans are to house nuclear waste permanently in underground facilities. In the near-term however, nuclear waste is stored in temporary storage facilities at various sites around the country. Federal and state regulations require periodic inspection of these storage facilities to insure storage vessel integrity and ver...

Evaluation of Disposal, Recycling, and Clearance Scenarios for Managing ARIES Radwaste after Plant Decommissioning

The wealth of experience accumulated over the past 30-40 years of fusion power plant studies must be forged into a new strategy to reshape all aspects of handling the continual stream of radioactive materials during operation and after power plant decommissioning. With tighter environmental controls and the political difficulty of building new repositories worldwide, the disposal option could b...
