TS 5.7,
High Radiation Area, required that each
HRA with dose rates >100mrem/hrat 30 cm but <1000 mrem/hr at 30 cm be barricaded and conspicuously posted as a
HRA. Contrary to this, on March 11, 2009, a ladder installed in the Unit 2 reactor building allowed access to a valve approximately 15 above the floor and was not barricaded and conspicuously posted as a
HRA. Dose rates on the valve were180 mrem/hr at 30 cm. The violation was discovered by an
HP technician performing surveys in the
RCA. Immediate corrective actions included barricading and posting the area around the ladder. This condition was documented in CR2009102730. This violation is of very low safety significance because there was no
substantial potential for overexposure and the licensees ability to assess dose was not compromised
