By 1/4th, do you mean 1/4th of nuclear? Sure, I'm totally happy with that. Once EROI is high enough, further improvement has only marginal effect. If EROI of PV is 10 (say) and nuclear is 40 (say), that just means nuclear is 1/10 - 1/40 or .075 better than PV by this metric. The contribution of this to the cost difference is minor, and is swamped by the other contributions to the cost of nuclear.
