EN Revision Text: AGREEMENT STATE REPORT - DAMAGED SEALED SOURCE

The following was received via email from the Georgia Radioactive Materials Program:

"During a routine 6 month leak test, a sealed source Cs-137 vial [0.035 milli-Curie] failed the leak test. [Leak Test Results: less than 0.005 micro-Curie.] Damage was detected on the vial and the source was immediately placed back into its shielded container and sealed with tape. All potentially contaminated items such as gloves were triple bagged, sealed, and labeled and placed in a shielded storage container in the hot lab. Area surveys and wipe tests were conducted and no contamination was found. The licensee is obtaining quotes for disposal and will follow up when the source has been disposed of."

EN Revision Text: AGREEMENT STATE REPORT - CONTAMINATION OF MEDICAL WORKER

The following was received from the Illinois Emergency Management Agency (the Agency) via email:

"The Agency was contacted at approximately 1230CDT on July 28, 2021 by GE Healthcare to advise that one of their employees required unplanned medical treatment due to a laceration and radioactive contamination. A glass vial containing approximately 4 milliCurie of Indium-111 oxyquinoline was being manipulated by a technician at the licensee's Arlington Heights facility when the neck of the vial broke. The broken glass cut the employee's finger and resulted in contamination of the wound with the radiopharmaceutical. The employee has since been treated, released and is estimated to have approximately 0.2 micro-Curie of non-removable contamination remaining within the wound. The amount of radioactive material involved will not result in occupational exposures exceeding the applicable limits. No permanent injury or deleterious effects are expected from the radioactive material. No other reportable exposures to medical staff occurred as a result of this incident."

Illinois Item Number: IL 210021

AUTOMATIC REACTOR TRIP

"At 1026 EDT on 8/3/21, with Unit 1 in MODE 1 at 100 percent power, the reactor automatically tripped due to low reactor water level. The low reactor water level condition was due to a loss of both reactor feed pumps. The cause of the loss of feed pumps is under investigation. Additionally, the low reactor water level resulted in the automatic actuation of High Pressure Coolant Injection (HPCI) and Reactor Core Isolation Cooling (RCIC) systems, and Containment Isolation Valves (CIVs) in multiple systems. All safety systems responded normally.

"Operations responded and stabilized the plant. Reactor water level is being maintained via RCIC system. Decay heat is being removed by discharging steam to the main condenser using the turbine bypass valves. Unit 2 is not affected.

"Due to the Reactor Protection System actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). It is also reportable under 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the HPCI and RCIC systems and CIVs. There was no impact on the health and safety of the public or plant."

The Licensee notified the NRC Resident Inspector. The Unit will proceed to Mode 4 while the cause of the loss of feed pumps is under investigation.

OFFSITE NOTIFICATION - INADVERTENT SIREN ACTUATION

"At approximately 1539 CDT on 8/3/2021, the Braidwood Station Main Control Room was notified of the inadvertent actuation of 17 Full Sounding sirens affecting Braidwood Station in Will County Illinois while testing other sirens. Will County EMA inadvertently actuated the sirens on 08/03/2021 at 1440 CDT.

"This event is reportable per 10CFR50.72(b)(2)(xi), News release or Notification of Other Government Agencies. This is a 4 Hour Reporting requirement.

OFFSITE NOTIFICATION - INADVERTENT SIREN ACTUATION

"At approximately 1539 CDT on 8/3/2021, the Dresden Station Main Control was notified of the inadvertent actuation of 17 full sounding emergency response sirens affected Dresden Station in Will County Illinois, while testing other sirens. Will County EMA inadvertently actuated the sirens on 8/3/2021 at 1440 CDT.

"This event is reportable per 10 CFR 50.72(b )(2)(xi), News Release or Notification of Other Government Agencies. This is a 4-Hour Reporting requirement.
