NEUP CINR-22-26888: Telescopic Control Rod for Significant Reduction in HTR Height and therefore Cost

We propose a design for a small modular High Temperature Reactor (HTR) control rod that extends telescopically, consisting of ~5 concentric annuli that nest together above the core when withdrawn. This compact component substantially reduces the length of the depth of the silo. We will perform modelling and experimental testing to develop the control rod to evaluate feasibility, plus perform a cost-benefit analysis, with a view to its inclusion in both pebble bed and prismatic HTR designs.
