SCONE reads ACE libraries: build nuclearData.materials entries from these nuclides using ZAID plus a temperature/table suffix that exists in your aceLibrary, with number densities in atoms/barn-cm. See the SCONE nuclear data tutorial and the NRDP library reference.

Notes

N-14 is 99.6% of natural nitrogen. The N-14(n,p)C-14 reaction produces long-lived C-14 (t½ = 5,730 y), relevant for waste and environmental dose calculations.
