Abstract.  The Compact Reversed Shear Tokamak `CREST' is a cost competitive reactor concept based on the reversed shear high beta plasma and a super-heated steam cycle which makes a high thermal efficiency ($\eta$ = 41%) possible. The moderate aspect ratio (3.4) and the elongation (2.0) of the CREST are similar to the ITER advanced mode plasma. The current profile control by neutral beam current drive stabilizes the ideal MHD activity up to $\beta_{\mathrm{N}}^{}$ = 5.5. The CREST could generate about 1.2 GWe electric power with a competitive cost.
