This is meant for electric potential NOT electric potential energy.

What'd be more important is the atomic number rather than nucleon number (you can't do this accurately without the atomic number.) You could always approximate Z=\frac{A}{2} since that's the locus about which many lower-mass ones lie, but yeah.

Anyway, if you have the number of protons, you can get the charge density of the nucleus
If you have the charge density, and assume spherical symmetry, you can integrate over shells, something along the lines of
E = \int{V(r)dq} = \int \frac{kQ_{\textrm{enc}}}{r}dq
where you should put together a correct shell element for dq.

All that assumes a uniform charge density ofc- it also only returns the electrostatic potential energy in its purest form and isn't considering any other potentials involved.
