Date: 07/29/94 Fredericksburg,Virginia (General Licensee) Subject: Lost Radioactive Source Reportable Event Number: N/A Discussion: On July 29, 1994, Book Crafters, Inc. located in Fredericksburg, Virginia, notified Region II of the apparent loss of a generally-licensed static eliminator containing approximately five millicuries of Polonium-210. This loss was discovered when the supplier of this device sent a replacement device and requested that the old device be returned. After a search of this facility, the licensee determined that the device was lost. Regional Action: Region II will followup on this event upon the receipt of a written report from the licensee. The written report was to be sent to Region II on July 29, 1994. Contact: L. Franklin (404)331-5788 PRIORITY ATTENTION REQUIRED MORNING REPORT - REGION IV AUGUST 1, 1994 Licensee/Facility: Notification: Nebraska Public Power District MR Number: 4-94-0072 Cooper 1 Date: 08/01/94 Brownsville,Nebraska SRI Telecon Dockets: 50-298 BWR/GE-4 Subject: THROUGH-WALL LEAK IN THE REACTOR EQUIPMENT COOLING (REC) SYSTEM Reportable Event Number: N/A Discussion: On July 29, 1994, during a tour of the plant, a licensee employee noted that water was dripping from a 12-inch REC pipe. Further investigation by the licensee identified that there was a through-wall leak in the piping. The licensee replaced the section of piping that was leaking and forwarded the removed section to General Electric (GE) for analysis. GE's analysis indicated that the location of the crevice cracking was in the areas where a backing ring was used at weld joints during original construction of the system. In addition, GE noted that sodium nitrates, used by the licensee as a corrosion inhibitor in the late 1970s, contributed to the crevice cracking problem. The licensee is currently in the process of performing ultrasonic testing on approximately 66 similar weld joints in the REC system. The licensee has completed testing of 17 joints and has identified 4 indications that require evaluation. In addition to the REC system, the licensee plans on performing inspection of weld joints in the turbine equipment cooling (TEC) system. The TEC system is the only other system identified by the licensee where sodium nitrates were used as a corrosion inhibitor. Preliminary information indicates that the licensee had experienced leaking in the REC system in the early 1980s. At that time, GE informed the licensee that the potential for crevice cracking existed in the REC system; however, it appears at this time, that the licensee did not take any actions to address this problem. Regional Action: Routine followup. Contact: P. H. Harrell (817)860-8250
