Cameco Corporation (CCJ), a leading uranium refiner, witnessed a significant 5.19% surge in its stock price during Tuesday's trading session. This rally can be attributed to a combination of factors, including bullish sentiment around the nuclear energy sector and a strategic cooperation deal with Poland.

The broader nuclear energy industry experienced a resurgence in investor interest, with stocks across the sector rebounding from the previous session's AI-related sell-off. Companies such as Lightbridge Corp (LTBR.O) and Oklo Inc (OKLO.N) also saw gains, reflecting a positive outlook for nuclear fuel fabrication and recycling technologies.

Furthermore, Cameco's stock received an additional boost as Poland and Canada signed a nuclear power cooperation deal. This agreement is expected to strengthen the bilateral relationship between the two countries in the field of nuclear energy, potentially opening new opportunities for Cameco's uranium products and services.
