HIGH PRESSURE COOLANT INJECTION STEAM SUPPLY VALVE FAILED TO REPOSITION
"At 0934 CDT, while appropriately removed from service for pre-planned testing, the High Pressure Coolant Injection (HPCI) inboard steam isolation valve, MO-2238, valve position indication was found to be inadequate. As a result, MO-2238 was declared inoperable in accordance with Technical Specification (TS) 3.6.1.3. This resulted in a condition that caused the HPCI system to be inoperable.
"The cause of the inadequate valve position indication is currently being investigated. This report is being made pursuant to 10 CFR 50.72(b)(3)(v)(D).
"The NRC Resident Inspector has been informed."

"The purpose of this notification is to retract a previous report made on 8/1/17 at 1700 (EDT) (EN 52881). NRC notification was initially made as a result of the High Pressure Coolant Injection (HPCI) inboard steam isolation valve, MO-2238, valve position found to be inadequate.
"Subsequent to the initial report, NextEra Energy Duane Arnold (NextEra) has determined that the condition observed on 8/1/17 for MO-2238 did not exist prior to removing the system from service for pre-planned testing, but was observed during post maintenance testing. Consequently, the failure does not meet the reporting requirements of 10 CFR 50.72 or 10 CFR 50.73.
"The NRC Resident Inspector has been notified."
Notified the R3DO (Riemer).

LOST GENERALLY LICENSED SOURCE
The following information was provided by the licensee via phone:
During a recent license renewal inquiry, it was discovered that during the decommissioning of the licensee's deepwater flow line in August 2017 a jumper with a generally licensed meter containing a nuclear source was removed and inadvertently scrapped. This event is under investigation by the licensee.
Roxar Flowmeter
Model number: RFM-SH7950
Source: Cs-137, 30 mCi
General License Number: 725736-16
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.
