ABSTRACT:
A support pin system (10) for fastening nuclear reactor guide tube flanges (14) to a nuclear reactor upper core plate (12) includes a support pin (16) having a lower portion (20) frictionally disposed within the upper core plate (12), while an upper section (24) is disposed within a through-bore (22) of the guide tube flange (14). The support pin (16) includes a threaded region (30) upon which is threadedly mounted a nut (32). In order to prevent retrograde rotation of the nut (32) relative to the support pin (16), a locking cap (46) is mounted upon the nut (32) and support pin (16) such that first crimped sections (48) are engaged within apertures (44) defined within the nut (32), while second crimped sections (54) are engaged within longitudinal grooves (50) defined upon the external surface of the support pin (16).
