Undervessel EquipmentMineral Insulated Cable UpgradesWith as many as 208 individual LPRM detector cables installed, the loops of organic LPRM cable can significantly impede undervessel work. Critical outage time is consumed and personnel exposure is accumulated while cable work is being performed. Furthermore, organic cable is subject to age degradation. Much of this time, exposure and risk of damage to cables and connectors can be eliminated with our mineral insulated (MI) cable assemblies. Our Reuter Stokes MI cable has environmentally qualified quick disconnect connectors and a 40-year life. Used in our NA-300 and NA-250 LPRM assemblies in the reactor environment, our instrumentation is durable and reliable. Since a variety of LPRM connectors and connector arrangements are used, GE offers all combinations of these in our MI cable and connector designs, all of which are qualified for use in a safety-related application.
SRM/IRM Drive Box Clevis BearingThe SRM and IRM drive equipment has a long history of reliable operation at boiling water reactors worldwide. However, these drive systems require frequent routine maintenance. The Reuter Stokes drive box clevis bearing reduces drive system maintenance requirements and improves system performance and durability. Cases have been documented in which the bearing that takes the load from the drive tube has split. Operation with a split bearing can be difficult and can induce extra vibration into the system. Vibration is one of the most prevalent causes of SRM/IRM detector failure. We address this issue by offering a heavy-duty bearing to reduce the probability of a split bearing.
SRM/IRM/WRNM Insertion ToolBecause of the unique space limitations undervessel and the installation and shipping requirements for SRM, IRM, WRNM and NA-250 LPRM detectors, GE has designed two insertion tools (one for SRM/IRM/WRNM detectors and one for NA-250 LPRMs) that simultaneously straighten and insert the detector into position in its dry tube. To install a SRM, IRM, WRNM or LPRM (NA-250), the cable must be uncoiled and inserted into its dry tube manually. Because of the close fit between the detector and dry tube, the cable must be very straight to avoid excess force and possible damage during installation. In the case of the SRM/IRM, the fiberglass cable-insulating sleeve adds to the difficulty in installation. Damage to the sleeve can cause detector shorting. Upon request, we will provide a cost/benefit analysis applicable to your specific plant operations.
SRM/IRM Drive Spring PlungerVibration is one of the most prevalent causes of SRM/IRM detector failure. The most important component dedicated to reduction of detector drive and shuttle tube vibration is the load-bearing adjustment screw or spring plunger. GE has designed a SRM/IRM drive spring plunger to help eliminate vibration and ensure continued operations. Replaces the original multi-piece component design with a more reliable one-piece construction
