Estimation of control rod worths by three dimensional methods is very time consuming. Even with the powerful computers, available today, it is difficult to perform multigroup (25 groups and above) calculations in three dimensions for large fast power reactors. In this paper, a simplified theoretical formula for estimating the total control rod wort...

Context 1
... control rod worths in X-Y and R geometry are reduced with the reduction factors quoted in Table 3, for the presence of control rods above the core top. The control rod worths estimated by the simplified formula and that obtained from actual 3-D calculations are quoted in Table 5. ...

In this work, a novel method for calculating mesh singularity lines (chains of irregular edges in an otherwise structured hex mesh) in a 3D computational domain is presented. It explores how combining the medial object of a domain with frames can provide insights to the placement of singularity lines. The medial object's vertices, edges and surface...
