"Torrance Unified School District (TUSD) reported to the RHB [Radiation Health Branch] via email on March 29. 2016 regarding nine tritium exit signs the school district is unable to account for after construction at two of their sites (5 signs at South High School located at 4801 Pacific Coast Highway, Torrance, CA 90505 and 4 signs at North High School located at 3620 W 182nd St, Torrance, CA 90504). TUSD has notified the contracted construction company, Balfour Beatty Construction, regarding the incident and requested removal documentation for the 9 exit signs, which to date has not been provided.

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AGREEMENT STATE REPORT - DAMAGED MOISTURE/DENSITY GAUGE

The following information was received from the State of California via email:

"On 03/29/16, the California Office of Emergency Services (OES) contacted the RHB [Radiation Health Branch] via an email to notify them of a damaged moisture/density gauge. The gauge was a Troxler gauge, Model 3440, S/N 38618 containing 9 mCi of Cs-137 and 44 mCi of Am-241. The gauge had been run over by an excavator while the operator was taking a reading along the side of the road where the incident occurred. Per the licensee, the Cs-137 source was in the shielded position (at the time of the incident readings were taken over a standard block for counts) when the gauge was damaged. The licensee stated that a 20 foot area was cordoned off until the gauge was removed. Fire Department personnel were at the scene.

"Per the licensee, a Pacific Nuclear Technology (PNT) RSO arrived at the site, and confirmed a survey meter reading of 0.5 mRems at one meter from the gauge, which is considered normal for this type of gauge. It was also noted that the Cs-137 and Am-241 sources were intact. Survey of the area after removal of the gauge indicated background readings. The gauge was placed inside the transit cage and returned to the licensee's storage location. A leak test will be performed and the gauge will be disposed of in the near future. RHB will be following up on this incident."

UNUSUAL EVENT DECLARED DUE TO MAIN STEAMLINE HIGH HIGH RADIATION CONDITION

At 1545 CDT on 04/06/16 Browns Ferry Unit 3 declared and exited the declaration of an unusual event due to a main steam line high high radiation condition. Power to Unit 3 was reduced to 91 percent power. The high radiation condition alarm cleared at 1526 CDT. Browns Ferry Unit 3 reported that the high radiation conditions were due to resin intrusion from the condensate demineralizers into the reactor and hydrogen water chemistry was a potential contributor to the event. The cause is still under investigation.

The NRC Resident Inspector has been notified.

State and Local notifications were made.

Notified DHS SWO, FEMA Ops Center, NICC Watch Officer, FEMA NWC and Nuclear SSA (email).

* * * UPDATE FROM BILL BALL TO DANIEL MILLS AT 0034 EDT ON 04/07/2016 * * *

"At 1941 [CDT] BFN [Brown's Ferry] determined this notification to be potentially newsworthy due to receiving notification that counties [surrounding the plant] were alerted of this event. No plant conditions changed."

The licensee may issue a press release.

The licensee will notify the NRC Resident Inspector.

Notified R2DO (Nease).

REACTOR BUILDING AIRLOCK DOORS OPENED SIMULTANEOUSLY

"On April 6th, 2016 at 1337 [EDT] and 1343 [EDT] Secondary Containment became inoperable due to failure to meet a Surveillance Requirement (SR 3.6.4.1.3) on Unit 1 and Unit 2.

"The inoperability was caused when two separate sets of Reactor Building airlock doors were sequentially opened during a medical emergency to transport an individual. Each set of airlock doors was opened momentarily to allow passage.

"Secondary Containment was restored April 6, 2016 at 1344 [EDT] when the transport evolution was complete.

"This event is being reported under 10 CFR 50.72(b)(3)(v)(c) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment system."

The NRC Resident Inspector has been notified.
