05-11-2017 | On March 13, 2017 at 16:00 hours, an unattended opening into a room classified as a vital area was identified by Security management. The unattended opening was created when a physical barrier was removed during decommissioning work within a vital area. The cause was determined to be an inadequate procedure(s) such that this action was not recognized by station personnel as a potential breach of a vital area pathway, therefore no compensatory measures were initiated prior to main steam discharge piping elbow removal. Upon recognition, the appropriate compensatory measures were implemented and a one hour report of Reportable Safeguards Events under 10 CFR 73.71(b)(1) and 10 CFR 73.71 Appendix G Section I ( EN 52609) was submitted to the NRC. |

Fort Calhoun Station
3. LER NUMBER
2017 - 00 001
BACKGROUND
Fort Calhoun Station (FCS) is a two-loop reactor coolant system of Combustion Engineering design. Fort Calhoun Station (FCS) permanently ceased power operations on October 24, 2016 and as of November 13, 2016, all fuel was removed from the reactor vessel and placed into the FCS spent fuel pool and has so certified as required by 10 CFR 50.82(a).
In accordance with Regulatory Guide 5.62 Rev 1 Reporting of Safeguards Events the following information is submitted.
1. Date and time of the event: The Safeguards event was discovered on March 13, 2017, at 1600 hours0.0185 days <br />0.444 hours <br />0.00265 weeks <br />6.088e-4 months <br /> Central Daylight Time (CDT).
2. Location of event: The Safeguards event occurred at Fort Calhoun Station (FCS) in an area that was still classified as a Vital Area in FCS's Physical Security Plan.
3. Operating Phase: FCS was at 0 percent power and defueled with all fuel assemblies removed from the reactor vessel and placed into the FCS spent fuel pool for decommissioning efforts.
4. Safety systems affected or threatened: No safety systems were affected or threatened by the discovery of the unattended opening into the Vital Area. While still classified as a Vital Area in FCS's Physical Security Plan, no safety systems necessary for the plant's current mode of operation and configuration are present in the area.
5. Type of security force onsite: FCS maintains a proprietary security force.
6. Number and type of personnel involved: Ten individuals from FCS security management and site maintenance personnel were involved with the initial discovery of the safeguards event.
7. Method of discovery of incident: The Vital Area barrier degradation was discovered by FCS Security management during a maintenance pre-job walk down for decommissioning activities.
8. Procedural errors involved: Maintenance procedure "Tool Pouch/Minor Maintenance" did not provide adequate guidance to determine if a plant barrier impairment was necessary prior to performance of maintenance. The discovery of the deficiency is governed by Security procedure "Observation and Inspection of Security Barriers.
9. Immediate actions taken in response to event:
a. Implementation of compensatory security measures in the Vital Area b. A search of the Vital Area and a review of the appropriate alarm log(s) was performed. No suspicious activity was identified c. All work that could result in potential unattended barriers was placed on hold comments regarding burden estimate to the FOIA, Privacy and Information Collections Branch (T-5 F53), L.S. Nuclear Regulatory Commission, Washington, DC 20555-3001, or by e-mail to NEOB-1C202.

3. LER NUMBER
2017 - 00 001 d. A review of plant drawings, a walk down by Security staff and an alignment meeting between Maintenance and Security staff to confirm no other unattended opening existed e. All Critical Digital Assets (CDAs) were walked down in the Vital Area with no issues identified 10. Corrective action taken or planned:
a. A site wide communication on Security requirements was distributed to increase station personnel awareness b. A revision to station procedures "Tool Pouch/Minor Maintenance", "Maintenance Planning", and "Facilities Maintenance Process" to ensure aspects of Plant Barrier Impairments procedure are specifically addressed c. The Manager Maintenance to re-enforce the specific roles and responsibilities for Maintenance supervisors during decommissioning activities d. Maintenance supervisor's to establish/re-enforce the decommissioning project responsibilities between Maintenance Program Specialists and station Maintenance craft personnel 11. Local, State or Federal law enforcement agencies contacted: No law enforcement agencies were contacted for the Safeguards event. The NRC was notified for a one hour report of Reportable Safeguards Events under 10 CFR 73.71(b)(1) and 10 CFR 73.71 Appendix G Section I (EN 52609).
12. Description of media interest and press release: No media interest or press releases occurred for the Safeguards event.
13. Indication of previous similar events: The root cause associated with this Safeguards event (CR 2017-00870) identified previous occurrences during outages without security compensatory actions in place. No evidence of malicious activates were identified. Also, boundary, such as underground pathways, was discovered that was not monitored by intrusion detection equipment or observed by security personnel at a frequency sufficient to detect exploitation.
14. Knowledgeable Contact: Mr. Chris Heimes, Director Site Security, can be contacted for additional details.
