Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Geological work begins on Poland’s first nuclear plant
Project management firm Bechtel started site geological surveys for Poland’s first nuclear power plant project, the company announced on Wednesday.
Bechtel will conduct in-depth geological surveys at the Lubiatowo-Kopalino site in the Pomeranian municipality of Choczewo, in northern Poland. This is a key milestone for the country’s entry into nuclear power production, as the surveys will inform the suitability of the planned site.

Calculations and measurements are presented for direct capacitor charging from tritiated electrodes, efficiency in converting beta decay energy into electric current, the effect of geometry on charging current, and the dielectric engineering options/trade-offs. Experiments using 1.4 × 1012 Bq (38 Ci) of tritium provided a 148-nA short circuit (charging) current at 5300 V of open circuit voltage, giving 160-W peak electrical power, with 12.5% overall efficiency. Calculations are in good agreement with the measured voltage accumulated over time for the tritium capacitor.
