EN Revision Text: PART 21 - FAILURE OF SIZE 1 AND 2 FREEDOM SERIES FULL VOLTAGE REVERSING STARTERS

The following is a summary of information received from Paragon Energy Solutions:

On 3/29/2021, Dominion - North Anna Station has identified instances where size 1 and 2 starters have failed to function as expected in assemblies that were originally supplied by Nuclear Logistics LLC (NLI). The mechanical interlock exhibited binding that prevented the contactor from closing when energized. The identified failed starters are utilized in an application of operating Motor Operated Valves (MOV). This is an intermittent duty application.

The issue was identified on Eaton Starter Model AN56DN*, AN56GN*, CN55DN*, CN55GN* style starters and contactors with supplied date codes T4514 (week 45 of year 2014) and T4215 (week 42 of year 2015). Paragon is in the process of identifying the date codes to provide the specific information to the identified plants.

The following plants were supplied starters from September 2014 through October 2018: Beaver Valley, Columbia, Ergytech, Harris, Millstone, NEK KRSKO, North Anna, Prairie Island.

The component design that exhibited the failure was revised by the original equipment manufacturer (Eaton) in October 2018. There have been no reported failures of the interlock mechanism in vintages manufactured before September 2014 or after October 2018.

These recommendations are based on the specific application: The reversing starters and reversing contactors are typically wired in a configuration that will electrically lock out one of the contactors when the other one is being energized to prevent both contactors from being energized at the same time. Therefore, the mechanical interlock is not required to prevent both contactors from being closed at the same time when the electrical interlock configuration is being implemented. In this scenario, the mechanical interlocks are not required and can be removed.

The motor control centers that contain the mechanical interlock should be monitored to ensure that there is no binding during operation.

The evaluation being performed by Paragon is expected to be completed by May 29, 2021.

EN Revision Text: LOST, THEN FOUND, PACKAGE OF IODINE-131

The following is a summary of a phone conversation with the Licensee's Radiation Safety Officer (RSO):

RLS (USA) Inc was informed that a package, which was shipped via a common carrier, was delivered to the wrong address. The package, which contained a sealed source of 297 millicuries of I-131, was dropped off at approximately 0930 (EDT) to Valassis Anderson Printing Plant. The package was labeled with the correct address, however the common carrier delivered it to the wrong location. Valassis Anderson Printing Plant informed the Licensee (RLS) at 1330 that they were in possession of the mis-delivered package at which time the Licensee immediately picked up the package and brought it to their facility. The package was missing for approximately 4.5 hours. Upon inspection, the package was not damaged. Wipes taken were at background levels. A surface survey reading indicated 17 mrem/hr and the transportation index was .5.

The contents of the package are 1000 times the limit specified in appendix C to part 20.

The RSO performed a worst case scenario: If a member of the public held on to the package for 4.5 hours that would yield a dose of approximately 76.5 millirem. The more likely scenario is that a member of the public was at 3 meters from the package for 4.5 hours which would yield a dose of 2.25 millirem. It is estimated that a member of the public could have received a dose greater then 2 millirem in 1 hours. However, there is no way to confirm this.

The package originated from Jubilant Draximage, Canada.




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.

"This 60-day telephone notification is being made in accordance with 10 CFR 50.73(a)(1) and 10 CFR 50.73(a)(2)(iv)(A) to provide information pertaining to an invalid Engineered Safety Feature actuation signal.

"On April 1, 2021, at Waterford 3, while performing a replacement of power supplies on the Plant Protection System, a spurious signal caused a partial actuation of the Emergency Feedwater Actuation Signal. A partial Emergency Feedwater (EFW) logic trip path was met causing the opening of valves EFW-228A (EFW to SG 1 Primary Isolation), EFW-229A (EFW to SG 1 backup isolation), EFW-228B (EFW to SG 2 Primary Isolation), and EFW-229B (EFW to SG2 Backup Isolation).

"This inadvertent actuation was spurious and was not a valid signal resulting from parameter inputs. The 1992 Statements of Consideration (57 FR 41378) define an invalid signal to include spurious signals. Therefore, this actuation is considered invalid.

"This event was entered into the Waterford 3 corrective action program for resolution. This event did not result in any adverse impact to the health and safety of the public. The plant responded as expected.

"In accordance with 10 CFR 50.73(a)(1) a telephone notification is being made in lieu of submitting a written Licensee Event Report.

"The NRC Senior Resident Inspector has been notified."

EN Revision Text: PART 21 REPORT - VACUUM BREAKERS FAILURE TO CLOSE

The following is a summary of the report provided by Framatome Inc.:

Identification of Component: Siemens 5kV 1200A Vacuum Breakers - 5-DPU-350-1200-78

Nature of Defect:
Framtome reported during dedication testing / inspection that a batch of 5-DPU-350-1200-78 MV vacuum breakers exhibited sporadic failure to close upon both electrical and mechanical closure signals. This was entered in their Corrective Action Program and troubleshooting / testing was completed at the Siemens manufacturing facility. Using a high speed camera to troubleshoot, they determined the close latch does not have sufficient torsional force to consistently maintain the breaker close latch in the closed position during the closing cycle. In some instances the breaker will receive a close signal and the close latch will not maintain the breaker in a closed position and the breaker will fail to close. It has been observed in testing that this condition is sporadic and that subsequent attempts to close the breaker will result in a closed breaker. The issue has no impact on the breakers staying closed once they have successfully closed. The issue has no impact on the ability for the breakers to open.

Number and Location of Basic Components:
The reportable defect is similar to design on the 22 breakers delivered and 19 installed at St. Lucie Unit 1, during refueling cycle 30. St. Lucie was notified on May 28, 2021 by Framatome Inc. via telephone and email.

Corrective Actions to Date:
Preliminary evaluation determined a modification of the breakers is required to increase the torsion spring force acting on the close latch. Framatome is working with Siemens to develop a long-term solution to increase the torsional spring force acting on the close latch. An interim solution utilizing a revised spring retaining bracket could be deployed near-term.
