Access to the Unit 1 keyway is obtained by entering through a locked caged door which provides access to an opening to the keyway. The location of the gap created the potential for individual to bypass the cage door and gain unauthorized access to the opening by climbing on the structural steel. 10 CFR Part 20.1602 requires that in addition to the controls specified in 10 CFR Part 20.1601, Control of access to high radiation areas, the licensee shall institute additional measures to ensure that an individual is not able to gain unauthorized or inadvertent access to Very High Radiation Areas. Contrary to the above, the gap in the structural steel provided a method for an individual to gain unauthorized or inadvertent access to the opening. The licensee identified the gap during routine surveys and checks of LHRAs and initiated immediate corrective action to control the VHRA. The licensee removed the lock from the caged door and relocated it to the metal louver covers directly above the opening to the keyway. Additional chains were added to the covers to reinforce and secure the access point directly above the opening. Although this event involved the failure to appropriately control access to a Very High Radiation Area, this finding is of very low safety significance because there was no substantial potential for overexposure and the licensees ability to assess dose was not compromised. The immediate corrective actions were documented in PER 266769. The long term corrective actions include fabricating additional materials to secure the areang additional materials to secure the area +
