EN Revision Text: MANUAL REACTOR TRIP
"On May 6, 2021 at 1223 [EDT], Unit 1 was manually tripped from 60 percent power due to degrading main condenser vacuum. Unit 1 was in the process of decreasing power due to increased secondary sodium levels identified earlier in the day. The Operations crew entered the reactor trip procedure and stabilized Unit 1 in Mode 3 at normal operating temperature and pressure. All control rods fully inserted into the core following the reactor trip. This reactor protection actuation is reportable per 10 CFR 50.72(b)(2)(iv)(B). Auxiliary Feedwater pumps actuated as designed as a result of the reactor trip and provided makeup flow to the steam generators. The automatic start of the Auxiliary Feedwater pumps is reportable per 10 CFR 50,72(b)(3)(iv)(A) for a valid actuation of an ESF [Engineered Safeguards Features] system. Decay heat is being removed by the condenser steam dump system."
The electrical system is in normal lineup for shutdown conditions. There was no effect on Unit 2 operation. The NRC resident inspector has been notified.

EN Revision Text: AGREEMENT STATE REPORT - STOLEN AND RETURNED GAUGE
The following was received from the New York State Department of Health (the Department) via email:
"A regional inspector for the Department received an email at 0341 EDT on 5/7/21 from the RSO of a materials testing lab stating that a Troxler model 4640 thin [layer density gauge], serial number 722, containing 40 mCi of Am-241/Be and 11 mCi of Cs-137, was stolen from a job site in Bronx, NY. The operator left the device unattended for a short period of time and returned to find it missing. The device was in its locked position when it was taken. The area was canvassed, and the police were notified.
"On 5/7/21, the licensee received a phone call from [an individual] stating that they had the device and wanted the reward. The licensee paid the reward and the device is back in the possession of the licensee. The device appears to be in good shape, but it will be leak tested before it is put back into operation."
Event Report ID No.: NYDOH-21-02
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.

EN Revision Text: AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE
The following notice was received from the State of North Carolina Radioactive Materials Branch (RMB), via email:
"A portable nuclear density gauge was reported stolen out of a licensee's flatbed truck, sometime during the evening of May 5th. The gauge was reported as secured from unauthorized removal by two independent means and padlocked in its transportation case. The truck was parked in front of the personal residence of one of the licensee's authorized users overnight. The morning of May 6th, the authorized user noticed the gauge case missing with locks and chains broken. The authorized user immediately called 911 and notified the licensee's Radiation Safety Officer immediately, who in turn, notified the RMB who responded to the scene of the theft the morning of [May] 6th. RMB is preparing a press release in an effort to recover the gauge and its investigation is ongoing."
Durham Police Department was notified.
