Calculation Breakdown

  1. Applied FormulaCalculates the instantaneous prompt power jump ratio (P1/P0) following a positive or negative step reactivity insertion (rho < beta) before delayed neutron precursors have time to change.\frac{P_1}{P_0} = \frac{\beta_{\text{eff}}}{\beta_{\text{eff}} - \rho} = \frac{1}{1 - \rho_{\$}}
