| Title | Licensee-Identified Violation |
| Description | The following violation of very low safety significance (Green) was identified by Vermont Yankee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy, for being dispositioned as a Non-Cited Violation. Vermont Yankee Technical Specification 6.5.B requires, in part, that areas in which the intensity of radiation is greater than 1000 mrem/hour at 30 cm, but less than 500 rad/hour at one meter shall follow the requirements of a high radiation area as well as provide for a locked or continuously guarded entryway to prevent unauthorized entry. Contrary to the above, on October 22, 2008, a Quality Assurance (QA) person identified that a posted LHRA over the Control Rod Drive access tube into the Drywell (Reactor Building 252 elevation) was not being continuously guarded by an access control guard in lieu of a locked barricade. There was a posted access control guard in place at the time of discovery but the individual was not aware of his responsibility relative to high radiation area control for that specific potential access point. Technical Specification 6.5.A in part requires that areas in which the intensity of radiation is greater than 100 mrem/hour at 30 cm, but less than 1000 mrem/hour at one meter be barricaded and conspicuously posted and access controlled by requiring issuance of a RWP. Contrary to the above, on October 23, 2008, Vermont Yankee staff discovered a conveyer ramp used for the transport of lead shielding that was not conspicuously posted or barricaded. The ramp extended over the existing high radiation area boundary established at the Drywell equipment hatch, Reactor Building 252 elevation. Radiation Protection established a guard for the area until the ramp could be removed. Additionally, on November 23, 2008, Vermont Yankee identified that an area previously posted and controlled as a high radiation area was found un-posted during a routine survey in the RHR room, 213 elevation southeast corner room. The area was immediately secured until posting and a barricade could be established at the bottom of the RHR heat exchanger. These issues were identified in Vermont Yankees CAP as CR-VTY-2008-04294, CRVTY- 2008-04377, and CR-VTY-2008-05236. These issues constitute a finding of very low safety significance (Green) because no persons had unauthorized access to these areas while these conditions existed and therefore no unplanned exposures occurred |
