The following information was received via fax:
"This medical event (ME) was self-identified by the licensee during an audit. A patient who had undergone an iodine-125 (I-125) prostate brachytherapy procedure was reported to have a 'D90' dose of 43% of the written directive. The licensee radiation safety officer and physician are in contact regarding this ME. It is unknown at this time if the patient has been notified.
"The Department [Pennsylvania Department of Environmental Protection] is waiting for the required 15 day written report from the licensee. The Department will then conduct a reactive inspection."
PA Event Number: PA140017
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.
* * * RETRACTION FROM DAVID ALLARD TO DONALD NORWOOD AT 1641 EDT ON 7/28/2014 * * *
The following information was received via facsimile:
"Through an internal audit, it was initially thought that a patient who had undergone an iodine-125 (I-125) prostrate brachytherapy treatment in November, 2013 was believed to have had a 'D90' dose of only 43% of the written directive. However, based on a re-assessment by the licensee's Chief Medical Physicist, it appears that greater than 80% of the prostate volume received the prescribed dose.
"[The] reported medical event is to be retracted."

| Event Text PART 21 REPORT - NOTIFICATION OF DEFECTS ON 2 INCH BONNETS
The following information was received from Velan Inc by facsimile:
"SUBJECT NOTIFICATION: 2 INCH BONNETS, VELAN PART NUMBER 8943-014
"On May 16, 2014 [Velan] received notification from Westinghouse Electric Co. (WES) that 2 bonnets supplied by Velan to WES in early 2013 for installation at Comanche Peak exhibited the following issues:
- The bonnets were intended to be exact replacements for the bonnets built to drawing E73-020 Rev E (OEM is Velan) except for material change to SA-182 FXM-19. Bonnets were visually inspected when received at site. No issues were noted; both bonnets appeared to be identical.
- In April 2013, Unit 1 bonnet was installed in valve 1-8109. No issues were noted with the installation. The new bonnet was put into service.
-In April 2014, Unit 2 installation was scheduled to begin. After the disassembly of the valve, the old and new bonnets were compared. It was noted that the backseat dimensions are different between the 2 bonnets. The increase in backseat diameter on the new bonnet would cause the stem to not backseat. The decision was made to re-install the old bonnet and send the new bonnet back to the OEM, Velan.
"On June 10, 2014 the bonnet, identified in the last bullet above, arrived at Velan Plant 2.
"The review by the [Velan] Evaluation Committee was finalized on July 17 and concluded that:
-Four similar bonnets were delivered to WES on three different occasions in 1988 and early 90's
-The stem head diameter is 01.312 [inches] so, when opening, the stem may pass through the stem bore of the bonnet and not seat on the backseat.
-On opening, if the limit switches on the actuator do not function, the stem may enter the packing chamber. The packing may be deformed and a leak may develop. Stem travel is limited by the disc contacting the bonnet and/or the end of the stem thread stopping on the actuator drive nut.
-If the actuator and packing flange nuts are removed, there is the potential for the stem to blow out of the valve.
-The packing chamber depth will result in more packing being installed in the valve. This may result in a higher packing friction load on the actuator when operating and reduce the actuator margin.
-The smaller packing chamber will not affect safety. A different diameter packing may be required. The gland bushing diameter (01.744 inches) is less than the packing chamber diameter and will work correctly.
"These bonnets were fabricated against ASME Sec. Ill for installation in Class 2 systems. Not knowing exactly the nature of the application we cannot determine if the [above identified] potential issues may pose a significant safety hazard and therefore we have informed WES by way of a similar letter."

Reporting Organization/Supplier who made the original event report on 07/18/2014 reported to the NRC Operations Center that the Event Notification posted has a typographical error regarding the Velan, Inc part number described in the report. The original documentation provided was concerning Velan Part Number 8943-014 which was mistakenly transcribed as 6943-014 in the original report. This error has been corrected in this updated report.

"At 1454 EDT on 20 July 2014, Turkey Point Units 3 and 4 entered the Action for Technical Specification (TS) 3.7.4, Ultimate Heat Sink (UHS). The action was entered because UHS temperature exceeded the limit of 100 degrees F due to a natural event. This report is in accordance with 10CFR50.72(b)(3)(v)(B) because UHS capability to remove residual heat is impacted. At 1800 EDT the NRC verbally approved a natural event Notice of Enforcement Discretion (NOED) which allows the ultimate heat sink temperature to exceed 100 degrees F up to 103 degrees F. Unit power levels have been maintained at Unit 3 100% and Unit 4 95%.
