Valuation of nuclear reactor spent fuel using the HP 67/97 programmable calculator

This Note applies the spent fuel valuation procedure of R-2239-DOE to a programmable hand calculator (the Hewlett-Packard 67/97). A modest degree of flexibility enables the program user to examine the impact on spent fuel value of variations in almost 30 parameters (e.g., yellowcake price, reprocessing cost, timing of recycle, U-236 composition, etc.). This program can be used to calculate: the present discounted value (PDV) of 1 kg of spent fuel placed in interim storage and permanently disposed at some future time; the PDV of 1 kg of spent fuel placed in interim storage and reprocessed and recycled into an LWR (or LMFBR) at some future time; the reprocessing (or yellowcake) cost that yields a net zero spent fuel value (i.e., the breakeven cost) in any future year; the contribution to spent fuel value of its uranium and plutonium components; and the enrichment plant feed/product ratio and SWU requirements as a function of product, tails, and feed enrichment
