EN Revision Text: TRAVERSING IN-CORE PROBE A BALL VALVE INOPERABLE
"At 1320 EDT, during a Traversing In-Core Probe (TIP) run for a scheduled Local Power Range Monitors (LPRM) calibration, it was reported to the Main Control Room that TIP A would not fully retract to the In-Shield position. With TIP A unable to fully retract to the In-Shield position the TIP A Ball Valve was declared Inoperable due to not being able to close and meet its safety function in that configuration.
Furthermore the TIP A Shear Valve was previously declared Inoperable due to the Firing Fuses being removed. With the two valves Inoperable the penetration could not be isolated and Primary Containment boundary isolation could not be established.
"TIP A was subsequently manually hand cranked and placed back into its In-Shield position at 1333 EDT restoring TIP A Ball Valve Operable.
"This report is being made pursuant to 10CFR50.72(b)(3)(v)(C) based on control the release of radioactive material.
"The Senior NRC Resident Inspector has been notified."
* * * RETRACTION ON NOVEMBER 24, 2021 AT 1232 EST FROM LEVI SMITH TO BRIAN P. SMITH * * *
"The purpose of this notification is to retract a previous report made on October 14, 2021 (EN 55522). At 1320 EDT on October 14, 2021 while performing Traversing In-Core Probe (TIP) Machine Gain Adjustment in support of Local Power Range Monitor (LPRM) calibration, an unplanned inoperability of the TIP 'A' Primary Containment Isolation Valve (PCIV) was reported pursuant to 10CFR50.72(b)(3)(v)(C) by EN 55522. On October 14, it was reported to the Main Control Room that TIP 'A' would not fully retract to the In-Shield position. With TIP 'A' unable to fully retract to the In-Shield position, the TIP 'A' Ball Valve PCIV was declared Inoperable due to not being able to close and meet its safety function in that configuration. The TIP 'A' Shear Valve PCIV was previously declared inoperable due to firing fuses being removed.
"Further investigation determined that a "FAULT: MOVEMENT LIMITED" error was received. This TIP error condition did not present a primary containment isolation issue in the event of a primary containment isolation signal. The Automatic TIP Control Unit (ATCU) is designed to command the TIP drive mechanism to continuously retract a TIP probe to the in-shield position in the event of a containment isolation signal with this condition. In the event of a containment isolation signal, the TIP machine would withdraw the TIP detector back to the in-shield position and the TIP A ball valve PCIV would have closed to perform its safety function. Therefore, the inoperability of TIP 'A' ball valve reported under criterion 10CFR50.72(b)(3)(v)(C) was not met, and EN 55522 is hereby retracted."
The NRC Resident Inspector has been notified.

EN Revision Text: FOUND LICENSED RA-226 SOURCES
The following is a synopsis of a telephonic report from the RSO at South Dakota State University:
On about October 14, 2021, the University was contacted to collect two orphaned Ra-226 sources from a residence of a former employee. One source was within an Ionization Cell Model A-4149, the other was contained in a lead pig. Swipe surveys did not detect any leakage from the sources. Both sources are identical, 0.056 mCi Ra-226, Dated 09-66, Barber-Colman Company, Rockford, Illinois. There are no serial numbers to determine the original owner. The deceased employee also worked in the chemistry department at Southwest Minnesota State University.
The Radiation Safety Officer has properly secured the items and is herby notifying the NRC of the possession of this licensed material, which is allowed by their license.
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.
