Plans for Poland’s first nuclear power plant continue to progress
Building Poland’s nuclear program from the ground up is progressing with Poland’s first nuclear power plant project: three AP1000 reactors at the Choczewo site in the voivodeship of Pomerania.
The Polish state-owned utility Polskie Elektrownie Jądrowe has announced some recent developments over the past few months, including turbine island procurement and strengthened engagement with domestic financial institutions, in addition to new data from the country’s Energy Ministry showing record‑high public acceptance, which demonstrates growing nuclear momentum in the country.

The present paper describes the experimental setup for flow-induced vibration in a fuel pin bundle test section with flowing lead. The test section is a 37-pin mock-up representative of the GEN-IV ALFRED fuel assembly and is manufactured to investigate the turbulence-induced vibrations in the pins. The pins are instrumented with longitudinal strain gauges (SGs), and with three SGs per monitoring point, the displacement signal can be recovered in terms of amplitude and frequencies. To achieve this goal, a complex algorithm is implemented in the data acquisition control system of the test section. The test section will be installed in the Heavy Liquid metal Experimental loop for Nuclear Applications (HELENA) facility at the ENEA Brasimone R.C., in which a mechanical pump for lead circulation is present. The test matrix is proposed with the mass flow rate varying from 10 to 50 kg/s and a constant temperature of 450°C for all the tests. Briefly, the experimental procedure is presented to carry out the experimental campaign.
