| Event Description | {{#Wiki_filter:The following information was received via facsimile:
1.0 Name and address of individual informing the Commission: Zisimos Giatis Quality Assurance Manager Fluke Biomedical Radiation Management Services 6045 Cochran Road Solon, Ohio 44139 2.0 Identification of the Basic Component supplied which fails to comply or contains a defect: Customer Complaint 0065 identifies the inability of the customer to insert the detector into the sample volume to the depth defined in primary isotopic calibration report 958.350. The report and manual for the device state the detector is to be inserted to a depth that results in 0.125 inches of the detector body extending outside of the detector mounting flanges. This dimension was expanded to 0.25 inches for the detectors supplied with a removable rear end cap. The customer advised that when installing the detector per the above, the face of the detector would "bottom out" against the sample volume cap before being fully inserted, leaving a gap of approximately 0.3 inches in front of the detector mounting flanges. 3.0 Identification of the firm supplying the Basic Component which fails to comply or contains a defect: Fluke Biomedical Radiation Management Services 6045 Cochran Road Solon, Ohio 44139 (Formerly Victoreen, Inc.) 4.0 Nature of the defect or failure to comply and the Safety Hazard created: Because the insertion depth is a critical component of the sample volume, and thus the efficiency of the detector, the detector CPM to �Ci/cc conversion constant cannot be validated. The conversion constant supplied for the sample geometry will result in the detector either overstating or understating the radioactivity being monitored. 5.0 The date on which the information of such defect or failure to comply was obtained: The problem was discovered September 7, 2005. 6.0 Affective Facilities Diablo Canyon Nuclear Plant, California Jose Cabrera, Spain KEPCO, Republic of Korea KAERI, Republic of Korea Con Ed, Indian Point 2 7.0 Corrective Action: The primary calibration will be repeated and a revised insertion depth will be provided to the affected customers. The estimated time frame to complete this task is 6 months. 8.0 Advice related to the defect or failure to comply about the Basic Component that has been, is being, or will be given to purchasers: At the Diablo Canyon plant, the accident range gas channel is not required for plant operation, and has been declared inoperable. International customers are being advised that the response of their accident range gas monitors may be questionable and to verify the insertion depth used in their plant.
Entergy (Con Ed) Indian Point 2 will be notified of the situation, although their sampler is no longer being used. Notified the R1DO (Henderson), NMSS (Moore) and Part 21 (Tabatabai). }} |
