Speaking at the Economic Forum, a major international conference in Poland's southern mountain resort of Karpacz, Chludziński said the so-called small modular reactor (SMR) would help KGHM reduce its emissions and consequently cut production costs.
"This technology is currently undergoing tests, and still has to be certified," Chludziński told the conference on Wednesday.
He added KGHM was turning to SMR because the company's main objective was to achieve "a certain level of energy self-sufficiency in the sense that we want the power we obtain to be climate neutral."
KGHM has also secured a licence to extract copper from new sites in Poland's western Lubuskie province.
The planned mine in Bytom Odrzański is set to be the world's first-ever net-zero facility of its kind, according to Chludziński.
"We have to design it from scratch, but it is possible," he said.
"Energy will come from renewable sources, yet electrical machinery will also be employed," he added.
"This deposit can be mined for 20 years, so it has a big future for KGHM," Chludziński told conference participants.
Dubbed the "Polish Davos," Karpacz's Economic Forum is a three-day annual conference, previously held in Krynica, another mountain resort in southern Poland.
This year, over 3,500 guests from around the world have converged on Karpacz, including senior politicians, parliamentarians, business executives and culture leaders.
Chludziński said last month that KGHM had started making profit from its Chilean copper mine, Sierra Gorda.
