Etymologically, the entry records: From Latin nū̆cleus, a contraction of the adjective nuculeus, masculine of feminine nuculea (“pertaining to a small nut”) from nucula + adjectival suffix -eus, -ea, -eum. The Latin nucula + -āris adds up to nuculāris, a term that in English becomes nucular;… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is nuclear, spelled N-U-C-L-E-A-R, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
