CHEMICAL AGENT MONITOR (CAM) EXCEEDED LEAK TEST
CAM exceeded leak test. 62 nano curies of removable contamination (Ni 63) was detected on the drift tube module which is a component located in the CAM. 5 nano curies was the limit for a leaking source according to license condition 16D. Exterior and interior container showed no signs of contamination.
CAM has been bagged and placed in the Radioactive waste holding area.
The CAM originated in South Korea. The licensee is in the process of notifying the RPO in South Korea.

MONITOR WELL EXCEEDED TWO OF ITS THREE UPPER CONTROL LIMITS
A routine bi-weekly water sample collected on July 8, 1999, from monitor well 6MW46 exceeded two of its three upper control limits (UCLs). A confirmation sample was collected on July 9, 1999, which also exceeded two of the three UCLs. Monitor well 6MW46 was then placed on excursion status as per license Section 11.2 and its sampling frequency was increased to weekly. 6MW46 is a perimeter ore zone monitor well located approximately 480 feet north of the Mine Unit 6 boundary at the Christensen Mine, Campbell County, Wyoming. The nearest community is Linch, Wyoming, approximately 15 miles to the southeast.
Analysis
Date Chloride Conductivity (umhos/cm2) Alkalinity (mg/l) Uranium (mg/l)
7-8-99 21.0 1651 197.0 <0.4
7-9-99 20.7 1630 202.6 <0.4
The upper control limits respectively, are 20.3, 2427, 89.2 and Uranium has no UCL.
Over-recovery pumping of 15 gpm has begun in the wellfield nearest 6MW46.

DEFECTIVE RELAYS PROVIDED TO FOXBORO BY VENDOR
"Foxboro Co. has identified a potential defect with N-2A0-L2C-R or N-2A0-L2C-R with ECEP 10273, Contact Output Isolator cards that may contain specific NO152CK or CO147SS relays. These relays, supplied by Potter & Brumfield, were manufactured utilizing pure tin plated contact support arms. As a result, in low voltage, low current applications, the growth of tin whiskers between adjacent metallic surfaces of the contact support arms can lead to the establishment of a resistive shunt path. This shunt path would prevent the relay from functioning as designed. This potential defect is limited to only those relays supplied by Potter & Brumfield manufactured from 1 December 1981 to 31 December 1993.
"Foxboro is taking immediate corrective action to rectify the situation and will notify all Nuclear Utilities that have purchased this product from Foxboro during the time period affected and provide replacement relays."
The representative reported that two failed relays were identified after being returned by a foreign reactor facility.
