As shown in Table 1, industry-wide data indicates that average EUF for the supercritical peer group is higher than for the subcritical peer group by 1 percent (14.3 percent vs 13.3 percent), or a ...

The systems presented were all subcritical - that is, the refrigeration cycles were entirely below the critical point of CO2. Now, after a brief review of CO2 characteristics, comparing subcritical ...

Earlier this month, the US National Nuclear Security Administration (NNSA) announced that it had conducted a subcritical experiment with plutonium in an underground tunnel 300 meters below the Nevada ...
