NRC SURRY and NAPS List of CRs and Resolutions (R1)
Hi Phillip , as discussed few minutes ago, please see the following you might have verified these last year as provided by the licensee. (2013). I just need a kind of verification (Yes or No) of the following items since I am finishing up Surry and NAPS Staff Evaluation Report for Assessment of Flooding Walkdown. I already have response from Greg. Thanks for the help.
-V 1.1 Effectiveness of Flood Protection Features The licensee identified the lack of a periodic monitoring program for penetrations and conduit seals. The licensee plans to put in place programmatic controls for periodic inspections of conduit and penetrations seals by December 31, 2013.
The licensee identified that there was not a rigorous tracking control of yard and storm drain changes. The licensee plans to put in place programmatic controls for yard and storm drain changes by December 31, 2013.
1.1.1 Flood Protection and Mitigation Enhancements The licensee has implemented or planned the following enhancements that improve or increase flood protection or mitigation:
A new conduit seal would be installed in the Turbine Building by January 31, 2013. The licensee stated that adequate controls for ensuring that storm drain and yard changes would be in place by December 31, 2013. The licensee stated that adequate period programmatic controls for conduit and penetration seal inspection would be in place by December 31, 2013.
1.1.2 Planned or newly installed features The licensee did determine that changes were necessary by the flooding walkdowns.
- New conduit seal would be installed in the Turbine Building by January 31, 2013.
- Development of adequate controls for ensuring that storm drain and yard changes would be in place by December 31, 2013.
- Development of adequate period programmatic controls for conduit and penetration seal inspection would be in place by December 31, 2013.
1.1.3 Deficiencies Noted and Actions Taken or Planned to Address Licensee noted the following deficiencies and actions taken or planned to address the deficiencies: The licensee identified three deficiencies: (1) unsealed inaccessible manhole conduits which have an accessible conduit end in the Turbine Building, (2) unsealed conduits in two accessible manholes, and (3) the partially blocked storm drain inlets.
First, the conduit ends in Manhole 0-SE-MH-22 were not accessible and therefore not inspected and assumed to not be sealed. Because these conduits were not sealed at the Turbine Building end their condition was noted as a deficiency and was entered into the CAP. The licensee stated that the Turbine Building end of these conduits would be sealed by January 31, 2013.
Second, the ends of conduits were not sealed in Manholes 0-MH-SE-23 and 0-MH-SE-26 or at the Turbine Building ends of the same conduits and their condition was noted as a deficiency and entered into the CAP. Unlike Manhole 0-SE-MH-22, these manholes are accessible. The licensee stated that the manhole conduit ends will be sealed by July 31, 2013.
Third, the material conditions of the site storm drains were found to be unacceptable due to blocked or partially block storm drain inlets. The ability of the some storm drains to perform their designed function was not fully analyzed after yard changes occurred. Routine storm drain maintenance was found to be insufficient to ensure an unobstructed flow path to 2
the storm drains. The licensee noted this as a deficiency and entered it into the CAP. The licensee stated that periodic preventative maintenance of storm drains should be implemented and programmatic controls are needed to ensure the prevention of yard changes leading to flow paths being blocked. The licensee stated that the programmatic controls were to be in place by December 31, 2013. The staff assesses that the approach described by the licensee is appropriate but was not able to review the specifics of the programmatic controls that were to be developed.
1.1.4 Walkdowns Analysis The licensee stated that three deficiencies were identified: (1) unsealed inaccessible manhole conduits that have an accessible conduit end in the Turbine Building, (2) unsealed conduits in two accessible manholes, and (3) the partially blocked storm drain inlets. The licensee stated that the deficiencies would be addressed by December 31, 2013.
1.2 Inaccessible Features The licensee identified the following inaccessible features: (1) conduit ends in Manhole 0-SE-MH-22, (2) buried portions of the storm drains, and (3) two locked high-radiation areas with inaccessible penetrations. The licensee provided reasonable assurance that inaccessible features are available and will perform its credited functions.
The licensee stated that the inaccessible manhole conduit end condition was entered into the CAP due to safety considerations. The licensee stated the Turbine Building ends of these conduits would be sealed to ensure that the flood-protection function of this feature will perform its intended function. The licensee specified that these actions were to be completed by January 31, 2013.
The licensee provided an acceptable schedule, which the staff acknowledges, to complete corrective actions for identified deficiencies no later than December 31, 2013 by letter dated November 27, 2012. The staff acknowledges that the licensee committed by letter dated November 27, 2012, to seal the Turbine Building side of electrical conduits from Manhole 0-MH-SE-22, designated as inaccessible during site walkdowns, no later than July 31, 2013.

Hey Greg, please see the attached that you might have checked this list last year as provided by Jay or other licensee contact from the station (2013). I just need a kind of verification for the completion (Yes or No) of the following items since I am finishing up Staff Evaluation report for Assessment of Flooding Walkdown. Following items are all in the attached list and I just received this from my contact, thanks for the help. -V Effectiveness of Flood Protection Features 3
- One deficiency related to a lack of manhole cover seal and missing conduit seal for the turbine building was identified with evaluation and resulting corrective action due for completion by December 31, 2013.
Flood protection effectiveness, key findings, identified deficiencies
- Conduits from a manhole to the turbine building were not sealed and at the ends and corrective action was scheduled for completion by December 31, 2013.
- Improvements in flood protection systems and procedural enhancements were scheduled for completion on or before December 31, 2013.
- Identified several areas where improvements could be made including: redirecting roof runoff; door sweep installation; manhole gasket inspection and maintenance procedure; periodic inspections of conduit and penetration seals; programmatic controls of yard and storm drain changes; and, revisions to procedural steps in Abnormal Procedure protocols to include flash flood warning and basin water level monitoring. Improvements in flood protection systems and procedural enhancements were scheduled for completion on or before December 31, 2013.
- Identified unsealed manhole conduits leading to in the turbine building as the deficiency to be addressed by December 31, 2013. Observations entered into the CAP include redirection of roof downspouts, a new door sweep, inspect of gaskets, conduits and penetrations, control of yard and storm drains, and Abnormal Procedure enhancements.
Resolution of all observations was scheduled for completion on or before December 31, 2013.
