AGREEMENT STATE REPORT INVOLVING A LOST MOISTURE DENSITY GAUGE
The licensee while transporting a Campbell Moisture Density Gauge S/N MC1391 from one jobsite to another in El Paso, TX, discovered upon arrival that the tailgate of the truck was down and the transport case with gauge were missing. The loss occurred within a sixteen (16) mile radius of the intersection of Hawkins Blvd. and Montana Ave. The licensee acknowledged to the TX Department of Health representative that the instrument had not been properly secured prior to transport. The gauge contains two (2) sources, i.e., 50 millicuries Am-241/Be and 10 millicuries Cs-137.
The licensee informed local law enforcement and the TX Department of Health. TX Incident No. I-8338
**** UPDATE ON 5/17/06 AT 2250 EDT VIA E-MAIL FROM LATISCHA HANSON TO SANDIN ****
Incident # correction: It should be I-8337.
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 injured someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. |

CALIFORNIA AGREEMENT STATE REPORT- MOISTURE DENSITY GAUGE RUN OVER
Eberhart/United Consultants, Inc. located in Placentia, CA reported to the State of California at 1000 PDT on 05/17/06 that one of their CPN MC3 (serial number M390304918) moisture density gauge was run over at a work site; Fontana Speedway, 9300 Cherry Avenue, CA; at 0830 PDT. When the gauge was run over the gauge was in backscatter mode of operation. The casing of the gauge was destroyed. The area was cordoned off and the RSO for Eberhart/United Consultants, Inc. was contacted. CPN Maurer Technical Services came out to the site and took possession of the gauge and took it back to their facility located in Laguna Hills. Wipe test of the sources are clean and the sources will be leak tested. Maurer Technical Services reported that the shielding for the Cesium-137 source had been compromised. State of California representative stated the highest radiation reading from the gauge at one foot was 18 milliRem per hour. The gauge contains a 10 milliCurie Cesium-137 source and a 50 millicurie Am-241/Be source. The RSO will be giving retraining to all staff to cover the emergency procedures for this type of incident. |

HIGH PRESSURE TRANSMITTER FAILURE
"At 0715 CDT on 05120/06, the Plant Shift Superintendent (PSS) was notified of a failure of the C-333A Autoclave 2 North High Cylinder Pressure System (HCPS). During a normal cylinder heating cycle the operator noted that the cylinder pressure, as read on a local digital pressure Indicator and on a digital recorder in the Operations Monitoring Room (OMR), unexpectedly fell from 55 psia to a negative value on both instruments. A 14 ton cylinder containing [deleted] U235 assay uranium hexafluoride had been heating (TSR Mode 5) for approximately 8 hours when the failure occurred. The PSS declared the HCPS inoperable and TSR LCO 2.2.4.14B actions were implemented to place the autoclave in Mode 2, 'Autoclave Open and Out-of-Service'. The HCPS is a TSR system designed to minimize the potential of primary system integrity failure (cylinder rupture) during a pressure increase event by tripping the steam supply to the autoclave prior to reaching the Maximum Allowable Working Pressure (MAWP) of the cylinder.
"This event is reportable as a 24 hour event in accordance with 10CFR 76.120(c)(2)(i). This is an event in which equipment is disabled or fails to function as designed when: a.) the equipment is required by a TSR to prevent releases, prevent exposures to radiation and radioactive materials exceeding specified limits, mitigate the consequences of an accident, or restore this facility to a pre-established safe condition after an accident; b.) the equipment is required by a TSR to be available and operable and either should have been operating or should have operated on demand, and c.) no redundant equipment is available and operable to perform the required safety function.
"Work Request #5087574" submitted to troubleshoot and repair.

PART 21 - SULZER PUMPS, INC.
The licensee provided the following information via facsimile:
"Pursuant to Title 10, Code of Federal Regulations, Part 21, reporting requirements, Sulzer Pumps (US), Inc. is reporting a deviation from technical requirements for components to be used in nuclear safety related applications.
"Sulzer Pumps (US) Inc. owns and operates a centrifugal pump repair and manufacturing facility at 4126 Caine Lane, Chattanooga, TN 37421. On May 7, 2006 during manufacturing we became aware of what appeared to be weld repairs to two pump bowl castings to be used in a replacement Essential Service Water Pump we are manufacturing for the J. M. Farley Nuclear Power plant. The supplier for these castings is Stainless Steel Foundry and Engineering, 5110 North 35 th St., Milwaukee, WI 53209, (414) 462-7400.
"The Sulzer Pumps (US) procurement documents to the foundry required weld repairs to the castings be preceded by notification to us, submission for approval of both the proposed weld procedure (WPS) to be used, and the weld procedure qualification record (PQR). Weld maps are also required by our procurement documents.
"In the case of our PO # 08407520, we received material certifications from Stainless Foundry and Engineering which certified no welding was performed to the castings. During our inspection processes we discovered what appeared to be weld repairs not traceable to us or to the above named Stainless Foundry. Subsequent investigation by Sulzer Pumps (US) and foundry representatives concluded that undocumented and unapproved weld repairs were performed by the foundry.
"Additional research by Sulzer Pumps (US) identified other castings supplied by Stainless Foundry and Engineering which were used in orders previously processed and shipped by Sulzer. The documentation supplied by Stainless Foundry stated none of these castings had required weld repair by the foundry. Our records indicate the castings that have been supplied are impellers. However, based on the aforementioned discoveries they too may contain undocumented weld repairs. We have reviewed and identified the nuclear power plants where pumps using these castings were shipped which are listed below. They are: Indian Point, Cust PO# 4500533843, our job number 04JC1423; and E.I. Hatch, Cust PO# 6057240, our job number 04JC1505.
"All other castings from Stainless Foundry and Engineering that we received have been placed on hold and will be returned to the foundry. We are in the process of evaluating our options to obtain replacement castings." |

UNUSUAL EVENT - REACTOR TRIP OF BOTH UNITS DUE TO LOSS OF ALL OFFSITE POWER
The licensee experienced a reactor trip to Units 1 & 2 due to loss of all offsite power. This anomaly was believed to be from an overcurrent condition in a relay, and limited to the Catawba switchyard. The reactor tripped due to actuation of the reactor protection system (RPS), and all rods for both Units fully inserted as designed. The Unit 1 Pressurizer PORV did lift momentarily. The decay heat is being released through the secondary PORV's, and steam generator level is being maintained with the auxiliary feedwater system (AFW). Presently, Units 1 & 2 are in EAL 4.5.U.1 (Loss of Offsite Power to Essential Busses for greater than 15 minutes). The licensee indicated there are no steam generator tube leaks in either unit. The licensee activated the TSC at 15:50 EDT.
The licensee notified the NRC Resident Inspector, as well as State and local government.
* * * UPDATE FROM SI BILLENGER TO HUFFMAN AT 0152 EDT ON 5/21/06 * * *
The licensee terminated from the Unusual Event at 0140 EDT on 5/21/06 based on restoration of offsite power to all essential buses. The licensee is no longer in a Tech Spec cooldown LCO and both units have secured from further cooldown and have stabilized conditions in Mode 3. Both units are still on natural circulation with AFW cooling and decay heat removal through secondary PORVs.
The licensee will notify the NRC Resident Inspector. R2DO (Widmann), NRR (Ross-Lee), IRD (Blount), FEMA (Kimbrell) and DHS(York) have been notified |
