ALERT DECLARED DUE TO LOW OXYGEN LEVELS INSIDE CONTAINMENT
"Containment atmosphere oxygen level was measured at 18.4 percent. This is below normal habitability level. The cause of the low oxygen level is a nitrogen leak inside containment Nitrogen has been isolated from containment and operators are preparing to purge containment."
The licensee notified the State of California, local authorities and the NRC Resident Inspector.
Notified the DHS SWO, FEMA OPS, USDA OPS, HHS OPS, DOE OPS, DHS NICC, EPA EOC. Notified FDA EOC, NuclearSSA, FEMA NWC and FEMA NRCC SASC via email.
* * * UPDATE FROM ALLEN DURACHER TO VINCE KLCO ON 7/28/17 AT 2142 EDT * * *
The ALERT was terminated on 7/28/17 at 1819 PDT. The containment atmosphere was restored to normal conditions. The nitrogen source was isolated. The cause of the nitrogen leak into containment is under investigation.
The licensee will notify the NRC Resident Inspector. The licensee has notified the State of California and the local authorities. The licensee plans to issue a press release.
Notified the R4DO (Hay), NRR EO (Miller), IRD MOC (Grant).

NOTIFICATION TO OFFSITE AGENCY OF NON-ROUTINE FLOW OF FIRE PROTECTION WATER TO THE OHIO RIVER
"On July 20, 2017, a fire protection supply line at BVPS [Beaver Valley Power Station] Unit 1 experienced a mechanical joint separation. When the mechanical joint separated there was an unplanned flow of water from the fire protection line to the ground, which eventually re-entered the Ohio River via storm drains. The source of the water to the BVPS Unit 1 Fire Protection System is the Ohio River. The fire protection water was not treated with chemical additives. The water flow from this fire protection line was terminated on the same day.
"Due to the situation described above, FENOC [FirstEnergy Nuclear Operating Company] provided written documentation describing this occurrence to the Pennsylvania Department of Environmental Protection, (PADEP) on July 28, 2017.
"This offsite notification to PADEP requires a 4-hour report per 10 CFR 50.72 (b)(2)(xi).
"No press release is planned.
"The NRC Resident Inspector has been notified."

AGREEMENT STATE REPORT - DOSE RECEIVED EXCEEDED PRESCRIBED DOSE
The following information was received from the State of Florida via email:
"[The State of Florida] received a call from the [Mayo Clinic] RSO [Radiation Safety Officer] to report a medical event that occurred at Mayo clinic. While performing a 90cc volume liver ablation, a female patient was to receive a 340 Gy dose, but it was later discovered that the dose delivered was 800 Gy. The physician has been notified, and is contacting the patient to inform her of the overdose and verify that there are no unusual side effects. A written report from the RSO will be sent to this office before Aug. 11th detailing the cause of the incident and corrective actions to be taken.
"Incident Number: FL17-230"
The isotope involved is Y-90 [Yttrium-90] Spheres.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
