Dear Mr. Venable:
On July 13, 2007, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection atyour River Bend Station. The enclosed report documents the inspection findings, which were discussed at the conclusion of the inspection with you and other members of your staff.The inspection examined activities conducted under your license as they relate to safety andcompliance with the Commission's rules and regulations and with the conditions of your license.
The team reviewed selected procedures and records, observed activities, and interviewed personnel. Specifically, the team evaluated the inspection areas within the Radiation Protection Strategic Performance Area that are scheduled for review every two years. These areas are:*Radiation Monitoring Instrumentation
- Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems
- Radioactive Material Processing and Transportation
- Radiological Environmental Monitoring Program and Radioactive Material ControlProgram This inspection report documents one NRC-identified finding of very low safety significance(Green). However, because the finding was of very low safety significance and it was entered into your corrective action program, the NRC is treating this finding as a noncited violation consistent with Section VI.A of the NRC Enforcement Policy. If you contest the noncited violation in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, U.S. Nuclear Regulatory Commission Region IV, 611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011-4005; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington DC 20555-001; and the NRC Resident Inspector at the River Bend Station facility.

SUMMARY OF FINDINGS
IR 05000458/2007010; 07/09/2007 - 07/13/07; River Bend Station; Access Control ToRadiologically Significant Areas; Radiation Safety TeamThe report covered a 5-day period of inspection on site by a team of five region-basedinspectors. A finding of very low safety significance (Green) was identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using IMC 0609,
"Significance Determination Process". Findings for which the Significance Determination Process does not apply may be "Green" or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 3, dated July 2000. A.
NRC-Identified and Self-Revealing Findings
Cornerstone: Occupational Radiation Safety
- Green.
The team identified a noncited violation of 10 CFR 20.1902(a) becausethe licensee failed to post radiation areas in the radwaste building with a conspicuous sign or signs bearing the radiation symbol and the words "Caution,Radiation Area." The licensee posted radiation area signs only at the entrances to the different elevations of the building, instead of at the discrete radiation areas, even though most of the radwaste building was not a radiation area.
Dose rates in unposted radiation areas were as high as 15 millirems per hour.
As corrective action, the licensee posted the discrete areas. Additional corrective action is still being evaluated.The finding was greater than minor because it was associated with one of thecornerstone attributes (exposure control and monitoring) and the finding affected the Occupational Radiation Safety cornerstone objective, in that, uninformed workers could unknowingly accrue additional radiation dose. Using the Occupational Radiation Safety Significance Determination Process, the team determined that the finding was of very low safety significance because it did not involve: (1) ALARA planning and controls, (2) an overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to assess dose. Also, this finding had a cross-cutting aspect in the area of human performance and component of work control because the licensee did not coordinate work activities by incorporating actions to address the need to keep personnel apprised of plant conditions that may affect work activities.

2.RADIATION SAFETY Cornerstones: Occupational Radiation Safety [OS] and Public Radiation Safety [PS]2OS1Access Control To Radiologically Significant Areas (71121.01)
a. Inspection Scope
This area was inspected to assess the licensee's performance in implementing physicaland administrative controls for airborne radioactivity areas, radiation areas, high radiation areas, and worker adherence to these controls. The team used the requirements in 10 CFR Part 20, the technical specifications, and the licensee's procedures required bytechnical specifications as criteria for determining compliance. During the inspection, theteam interviewed the radiation protection manager, radiation protection supervisors, and radiation workers. The team performed independent radiation dose rate measurements and reviewed the following item:*Controls (surveys, posting, and barricades) of radiation areas The team completed 1 of the required 21 samples.
b. Findings
Introduction.
A Green noncited violation of 10 CFR 20.1902(a) was identified for thefailure to post radiation areas in the radwaste building with a conspicuous sign or signs bearing the radiation symbol and the words "Caution, Radiation Area."Description. While making observations in the radwaste building on July 10, 2007, theteam identified localized radiation areas in walkways in front of high radiation area and locked high radiation area doors which were not posted as radiation areas. The general area dose rates in front of Door RW106-G2 and RW65-G8 were 6 mrem/hr and 15 mrem/hr, respectively. The only radiation area signs to warn workers prior to entering the radiation areas were at the entrances to the different elevations of the radwaste building. The radwaste building is a large area and according to the licensee's surveys, only a small part of the total area had dose rates exceeding 5 millirems per hour.
Analysis.
The team reviewed the applicable guidance in NUREG/CR-5569, Revision 1,Health Physics Positions 036, "Posting of Entrances to a Large Room or Building as a Radiation Area," and 066, "Guidance for Posting Radiation Areas." Because the area was large and very little of it was a radiation area, the team concluded that posting only the entrances to the area, rather than the discrete areas, was not sufficient to inform radiation workers of radiological hazards in their work areas. The failure to post a radiation area is a performance deficiency. The finding was greaterthan minor because it was associated with one of the cornerstone attributes (exposure control and monitoring) and the finding affected the Occupational Radiation Safety cornerstone objective, in that, uninformed workers could unknowingly accrue additional
-4-radiation dose. Because the finding involved the potential for unplanned, unintended doseresulting from conditions that were contrary to NRC regulations, the finding was evaluated using the Occupational Radiation Safety Significance Determination Process. The team determined that the finding was of very low safety significance because it did not involve:
- (1) ALARA planning and controls,
- (2) an overexposure,
- (3) a substantial potential for overexposure, or
- (4) an impaired ability to assess dose. Also, this finding had a cross-cutting aspect in the area of human performance and component of work control because the licensee did not coordinate work activities by incorporating actions to address the need to keep personnel apprised of plant conditions that may affect work activities.
(H3.b)Enforcement. Part 20.1003 of Title 10 of the Code of Federal Regulations defines aradiation area as an area, accessible to individuals, in which radiation levels could result inan individual receiving a dose equivalent in excess of 5 millirem in an hour at 30 centimeters from the radiation source or from any surface that the radiation penetrates.
Part 20.1902(a) of Title 10 of the Code of Federal Regulations states that the licensee shall post each radiation area with a conspicuous sign or signs bearing the radiation symbol and the words "Caution, Radiation Area." However, on July 10, 2007, the team identified radiation areas in the radwaste building that were not conspicuously posted. As corrective action, the licensee posted the discrete areas. Additional corrective action is still being evaluated. Because the failure to conspicuously post radiation areas was determined to be of low safety significance and was entered into the licensee's corrective action program as Condition Report CR-RB-2007-03038, this violation is being treated as an noncited consistent with Section VI.A of the NRC Enforcement Policy:
