This following report was phoned in, followed by an email:
"On August 22, 2017, Chesapeake Urology, notified the Maryland Radiological Health Program (RHP) that a male patient was injected with 176.1 microCuries of Ra-223 (Xofigo) instead of 108.4 microCuries of Ra-223 (Xofigo); 62.5 percent greater than the prescribed dose. The wrong unit dose was handed to the authorized user for patient administration. The event occurred at approximately 0930 [EDT] hours on 08/22/2017 at the licensee's address of 21 Crossroads Drive, Suite 200, Owings Mills, MD 21117. Maryland RHP was notified by telephone at 1505 hours. Two patients were scheduled for treatment on August 22, 2017. Both doses were assayed in the morning. Each dose had the proper patient name on the lead pig and on each respective syringe. The incorrect dose was selected and injected without cross referencing the identity of the patient. The event was discovered at approximately 1130 hours when the second Xofigo dose was to be administered. The patient and the referring physician have been informed of the misadministration. A written notification from the licensee is expected in about a week. This is a preliminary notification."
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. |

"At 0210 CDT on August 30, 2017, Comanche Peak Nuclear Power Plant (CPNPP) Unit 2 experienced an unplanned loss of the Plant Computer System (PCS). The loss of the Unit 2 PCS resulted in a loss of emergency assessment capability to the CPNPP Technical Support Center (TSC) and Emergency Operations Facility (EOF) for greater than 60 minutes. As of 0530 CDT the Unit 2 PCS has been restored. Assessment capability has been verified to be available in the TSC and EOF.
"This report is being made pursuant to 10CFR50.72(b)(3)(xiii), any event that results in a loss of emergency assessment capability, off site response capability, or off site communications ability.

| Event Text PART 21 REPORT - RELAY FAILURE NUTHERM MODEL 700DC
The following excerpted report was received via fax:
"On the basis of our evaluation, it is determined that Nutherm lnternational, Inc. does not have sufficient information to determine if the subject condition would, or has, created a Substantial Safety Hazard or would have created a Technical Specification Safety Limit violation as it relates to the subject plant applications.
"On 8/28/2017 Cooper notified the NRC of a reportable condition under 10CFR Part 21. An Allen Bradley relay base model 700DC exhibited early failure after 133 hours of service. This relay, model 700DC, has been dedicated/qualified for multiple applications for various plants.
"The Allen Bradley 700DC series relay coil failed after 133 hours of service. This failure was determined by Cooper Nuclear Station to have been a component infant mortality likely caused by a manufacturing flaw that likely occurred due to a tensioning issue at the start of the coil wire winding process. Failure of the coil will result in failure of the relay, which could result in a safety hazard.
"Nutherm International, Inc. has concluded its review of all procurements of the 700DC series relays that use the coil in question and have found forty-nine (49) units shipped to customers which could potentially have this defect: Nebraska Public Power Cooper Nuclear Station and Indiana Michigan Power Company Donald C. Cook Nuclear Plant.
"Initial actions of determining the units affected were completed 8/30/2017. The impacted customers were notified of this condition 8/30/2017. Nutherm International, Inc. does not have sufficient information to determine this condition would, or has, created a Substantial Safety Hazard or would have created a Technical Specification Safety Limit violation as it relates to the subject plant applications. Nutherm has no current orders for these units and has no units in stock. No further actions will be taken at this time.
"This issue has been identified as a 'component infant mortality' failure caused by a manufacturing flaw. The manufacturing flaw appears to be a random failure and was identified by Cooper Nuclear Station as likely to have occurred due to a tensioning issue at the start of the coil wire winding process. Failure of the coil would be expected to occur within a few days of operation. The units that have been installed and in operation for more than two months could be considered to not contain this random manufacturing flaw."

| Event Text INDEPENDENT SPENT FUEL STORAGE INSTALLATION FUEL OIL SPILL
"At approximately 1824 [CDT], the ISFSI was notified of a diesel spill of approximately 70 gallons onto gravel and concrete. The spill originated as a 500 gallon tank was being transported and fell from the forks. The pump on top of the tank was damaged causing the leak. No personnel were injured and there was no pathway to a waterway. Notification was made at 2045 to IEMA [Illinois Emergency Management Agency]. The reason for notification is due to 10CFR50.72(b)(xi), notification to off-site government agency. The spill was cleaned up by site personnel and supervised by the Environmental Manager."
The licensee will notify the NRC Resident Inspector. | |
