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.

The concept of a traveling-wave direct energy converter (TWDEC) to recover the energy of 14.7-MeV protons produced by D-3He fusion has been proposed. In TWDEC, the protons are velocity modulated in the modulator to form a bunched beam and then decelerated by the traveling wave excited in the decelerator. A proof-of-principle experiment of TWDEC is performed using a low-energy ion beam. Characteristics of velocity modulation and bunching are measured and compared with theory. It is demonstrated that the beam is decelerated by the traveling wave when the phase velocity and the phase of the wave are adjusted with respect to those of the bunched beam.
