AGREEMENT STATE REPORT - WELL LOGGING SOURCE ABANDONED

The State provided the following information via facsimile:

"Baker Hughs Intec abandoned a 2.5 Ci source of Cs-137 and a 5 Ci source of Am-241 down hole on March 13, 2006. The depth of the sources is between 14,423 feet and 14,430 feet. The hole has [been] back filled with cement to a depth of 12,095 feet to prevent reentry into the hole."

POTENTIAL UNSECURED ACCUMULATION POINT IDENTIFIED

"During inspections of the facility, NFS personnel identified an out-of-service equipment elevator and questioned if it contained any potential unsafe accumulation points. The elevator door was later opened and it revealed a pit area that was approximately 8-10 inches below the building floor level. This is considered a 1-hour reportable event because there is no [item relied on for safety or formal controls] in place to prevent a solution leak from entering this location. A solution leak to this area is considered a credible abnormal condition."

No actual material accumulation occurred. The licensee currently has compensatory measures in-place to prevent material accumulation in the area.

The licensee notified the NRC Resident Inspector.

FAILED FITNESS FOR DUTY TEST

A licensed employee supervisor had a confirmed positive for alcohol during a re-entry fitness-for-duty test. The employee's access to the plant has been blocked. Contact the Headquarters Operations Officer for additional details.

The licensee informed the NRC Resident Inspector.

TECHNICAL SUPPORT CENTER VENTILATION FAN INOPERABLE

"The Technical Support Center ventilation system was discovered to be non-functional at 1110 on March 13, 2006. The cause of the ventilation problem was determined to be damaged drive belts on the supply fan. The belts were replaced and the ventilation system supply fan was returned to service at 1253 on March 13, 2006. This condition is considered a Loss of Offsite Response Capability and is therefore reportable under 10CFR50.72(b)(3)(xiii)."

A corrective action request has been generated to follow remedial action.

The licensee notified the NRC Resident Inspector.

MANUAL REACTOR SCRAM AFTER OFFGAS SYSTEM FAILURE

"During a power ascension, the non-safety Augmented Offgas System experienced a failure which caused a Recombiner high temperature condition. To protect components of the non-safety Augmented Offgas System, station procedures require a manual scram of the reactor when this condition occurs. Station procedures were followed and the reactor was manually scrammed at 18:08. All rods fully inserted and all safety systems performed per design. Primary containment isolation systems responded properly resulting in an automatic isolation of Primary Containment Isolation System Groups 2 and 6 valves and a Reactor Building Isolation due to the transient low reactor water level condition caused by the scram.

"The plant is in a stable condition. Investigation is continuing."

No safety valves lifted on the scram, decay heat is being removed with the bypass valve, normal feed and condensate are maintaining reactor water level, and the electrical grid is stable on the startup transformer. The licensee notified the NRC Resident Inspector.

FAILURE OF ONE EMERGENCY SIREN

"The station received a report that a siren was sounding. The station investigated and determined that one siren, EBR#3 was intermittently activating. A communications team was dispatched to remove this siren from service for repairs. The Louisiana Office of Homeland Security and Emergency Preparedness was notified in accordance with station procedures. Responsible personnel at that facility determined that no further action was required since the activation involved only one siren."

The siren is in East Baton Rouge Parish and was reported to the site by the Sheriff. The failure is suspected to be a circuit board problem.

The licensee notified the NRC Resident Inspector.
