- 1. Decay heat per fuel assembly is presented A decay heat value that is equal to or greater than the appropriate decay heat load limit 2.1. The polynomial coefficients associated for decay heat load 1.81 < decay heat 3.26 are applied to the UNVENTILATED OVERPACK MPC-32M decay heat load range of 0.83 < decay heat 3.26 Holtec Letter 5014951 Attachment 6 Page 1 of 2
