Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

A large oil-free reciprocating pump was developed for high level tritium service. The pump is a water-cooled, single acting, four stage vertical piston vacuum pump. The characteristics of the pump were measured with H2, D2, He and N2 gases. Pumping speeds were approximately 180 M3/hr for these gases and almost constant above 10 torr of suction pressure., while it drastically dropped in the lower pressure region. The pump combination with a magnetic levitated turbomolecular pump worked well with N2, however He, D2 and H2 could not be pumped well due to poor matching of the characteristics of these pumps.
