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 nuclear fuel cladding undergoes severe thermal shock during reflooding of the nuclear core after a loss of coolant accident (LOCA). The purpose of this work is to evaluate the resistance of SiCf-SiCm composite cladding to such thermal shock events. In order to achieve this goal, a nuclear grade SiCf-SiCm composite tube, manufactured by General Atomics (GA), was quenched from an outer surface temperature of 1000 ºC into room temperature (RT) water and hot water. The composite tube was heated by a tungsten rod placed inside the tubular sample to simulate the fuel pellet. The tungsten rod was heated to a centerline temperature of 1400 ºC by an induction coil. To monitor the progressive damage of the SiCf-SiCm composite tube, the acoustic emission (AE) technique is used to acquire the acoustic signals during the test. The samples quenched into RT water showed visible cracks while the sample quenched in hot water did not. Some of the AE signals are related to cracks in the material during quenching. After quenching, the burst strength of the SiCf-SiCm composite tube is measured using a bladder technique. Results show that the SiCf-SiCm composite tube retains more than 88% of its strength after quenching.
