At 1511 CDT, injured person was transferred off-site by medical helicopter.

This four-hour notification is being made pursuant to 10 CFR 50.72(b)(2)(xi), event or situation related to health and safety of on-site personnel for which notification to other government agencies has been made. NRC Resident informed. Due to this event, 1/2 gallon of gasoline was discharged to the Missouri River. The spill was reported to the State of Nebraska on 6/30/2011. This condition is also being reported pursuant to 10 CFR 50.72(b)(2)(xi) for News Release or Notification of Other Government Agency. Applicable state agencies have been notified per plant procedures. The injured person is a plant employee and was injured while refueling a portable generator. The injured person suffered burns to the forearms and neck. The licensee intends to issue a press release. The NRC Resident Inspector has been notified.

Communications has been lost to 21 sirens out of 101. The loss of communications does not allow the activation of the sirens. Almost all of Harrison County and Pottawattamie County in Iowa are without communications to the sirens. There are compensatory measures in place to ensure notification by local law enforcement in case of an actual emergency to inform the public in these areas. This is being reported per 10CFR50.72(b)(3)(xiii) for 'Any event that results in a major loss of emergency assessment capability, off site response capability, or communications capability'. An attempt is being made to reboot the siren's communication system in order to restore the sirens. During the reboot, sirens in Washington County, Nebraska, will also lose communications and therefore will not be functional. Local Law Enforcement has been notified in Washington County to perform compensatory measures in case of an emergency. The NRC Resident Inspector has been informed.

During a review of environmental qualification records for reactor containment building electrical penetrations, six penetrations were identified that may not provide an adequate seal during worst case (Design Basis Accident (DBA)) conditions as required. These penetrations are through wall from the containment into the auxiliary building. The conditions that could cause degradation of the electrical penetration seals are not applicable to this operating mode. The station is currently in a refueling mode. This event was identified on March 2, 2012. The reportability was confirmed on May 1, 2012 at 1502 CDT. The current penetration configuration has existed since the plant was built. The area of concern is that the Teflon connections may degrade under conditions of high radiation and high temperature during a DBA event. The licensee is investigating the extent of the condition and repair techniques. The licensee notified the NRC Resident Inspector.

* * * UPDATE FROM ROBERT KROS TO PETE SNYDER AT 1523 ON 6/26/12 * * * 

On review of CR 2012-01947 by a new Project Manager, who was brought in as a subject matter expert on HELB/EEQ, and issue was identified with the 530 primary containment electrical penetration feed-throughs used for non-CQE devices. The CR (Condition Report) correctly notes that under the original accident testing, the Teflon seals failed, and water was noted leaking from these penetrations. On further review, the following was noted: Due to the design of the penetration feed-throughs, when the inboard Teflon seal fails (as it is expected to, due to high level of radioactivity in the primary containment, following a Loss of Coolant Accident (LOCA)), the atmosphere of the primary containment will be introduced to the penetration assembly, first through the failed seal or seals, and then through the weep hole between the inboard and outboard seals of the feed-through. This will put the same high level of radioactivity in direct contact with the outboard seals, resulting in the failure of its Teflon Seal. This would result in approximately 530 breaches of the Primary Containment during post LOCA conditions. The existing vendor analysis does not assume any contribution to the outboard seal exposure from the mixing of containment atmosphere with the penetration air after the failure of the inboard seal. This is probable, as each feed-through has a weep hole. Once the inboard seal fails, the penetration will be filled with containment atmosphere to equalize the pressure, which will bring the associated noble gas and Iodine fraction in proportion, into the penetration. The licensee notified the NRC Resident Inspector. Notified R4DO (Clark)

• * * UPDATE AT 1748 EDT ON 7/17/12 FROM MOECK TO HUFFMAN * * *

During the extent of condition review for CR 2012-01655 and 2012-01947 additional penetration feed-through assemblies were identified that are subject to the same failure mechanism. These penetrations are associated with the containment sump recirculation isolation valves, and also associated with the personnel air lock. The licensee notified the NRC Resident Inspector. Notified R4DO (Walker).

During a review of plant installed instrumentation racks inside containment, two instrument racks were identified that were over the analyzed weight for the seismic analysis. The instruments on these racks are used for reactor coolant pressure transmitters that are part of the Reactor Coolant System (RCS) pressure boundary, as they are connected via instrument lines to the RCS with no remote closure capabilities. A failure of these racks during a seismic event due to the excessive weight could result in an unisolable leak from the RCS within containment based on engineering judgment. This results in the RCS principal safety boundary being in a degraded nonconforming condition as the Updated Safety Analysis Report (USAR) specified Class 1 requirement is not being met for the current seismic design. Further engineering analysis is in progress to address the weight issue for these racks and mounting requirements. The plant is shutdown and in Mode 5 with the reactor vessel head removed, so RCS is not intact and not required to be for current plant conditions. This report is being made in accordance with 10CFR72(b)(3)(ii)(A) for a degraded condition. The licensee has notified the NRC Resident Inspector.

• * * UPDATE ON 8/3/12 AT 1708 EDT FROM JULIE BISSEN TO DONG PARK * * *

On June 4, 2012, at 2059, Fort Calhoun Station made an 8-hour non-emergency notification for a degraded condition. Subsequent internal review has determined that the initial reporting criterion for degraded condition, 10 CFR 50.72(b)(3)(ii)(A), was incorrect. The instrument racks were identified as being over the analyzed weight for the seismic analysis. This is an unanalyzed condition, not a degraded condition. The report made on June 4, 2012 should have been made under 10 CFR 50.72(b)(3)(ii)(B), unanalyzed condition. The licensee has notified the NRC Resident Inspector. Notified R4DO (Werner).

A planned outage of all FCS (Fort Calhoun Station) sirens is to occur at 0900 CST today to replace required router power supplies.
