60 Years of U: Perspectives on resources, demand, and the evolving role of nuclear energy
Recent years have seen growing global interest in nuclear energy and rising confidence in the sector. For the first time since the early 2000s, there is renewed optimism about the industry’s future. This change is driven by several major factors: geopolitical developments that highlight the need for secure energy supplies, a stronger focus on resilient energy systems, national commitments to decarbonization, and rising demand for clean and reliable electricity.

A continuous duty cryopump system has been designed and developed that comprises a self-contained cryopump for installation into a vacuum chamber, and a microprocessor controller for automatic operation. This deuterium pump has two units in a single housing, arranged so that one is pumping while the other is regenerating. Liquid helium-cooled and finned sections in each unit pump deuterium by condensation, and an integral collector pump captures the regenerated gas. A microprocessor unit controls distribution of liquid and gaseous helium for conditioning the pumping units and operation of remote actuators for regeneration. Software provides fully automatic, timed sequencing of the repetitive cryopump events, which can be reprogrammed through a keyboard. An override allows manual operation, and interlocks prevent cryogen lockup. The pump is being prepared for testing this Spring.
