Recent surveys confirm high levels of U.S. nuclear support
Surveys have consistently indicated that public support in the United States for the use of nuclear energy has been increasing in recent years. Four recent surveys continue to suggest that near-record-high numbers of Americans support nuclear energy. However, the survey results differ—sometimes widely—in the details of their findings.

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.
