The creep test results show that the accelerated creep stage does not occur in the creep process of salt rock. Therefore, the nonlinear viscoplastic body in the creep model does not work. In other words, parameters m, n, σ s and η B0 are not considered in the calculation. are not considered in the calculation.
Compressed Air Energy Storage (CAES) was seriously investigated in the 1970s as a means to provide load following and to meet peak demand while maintaining constant capacity factor in the nuclear power industry. Compressed Air Energy Storage (CAES) technology has been commercially available since the late 1970s.
The 110 MW McIntosh plant can operate for up to 26 h at full power. The compressed air is stored in a salt cavern. A recuperator is operated to reuse the exhaust heat energy. This reduces the fuel consumption by 22–25% and improves the cycle efficiency from ∼42% to ∼54%, in comparison with the Huntorf plant.
