    摘要： An electrode probe for measuring the electrochemical potential of a surface at a location of interest in a boiling water reactor. The probe has a monolithic sensor configuration built into a single stainless steel mineral insulated (MI) cable. This monolithic sensor can be used as a switch to detect when the appropriate concentration of dissolved hydrogen required to provide IGSCC mitigation is present at any location inside the reactor. Using the sensor switch, it is possible to in situ instantly determine the minimum hydrogen level required to reach the IGSCC protection potential. The sensor configuration consists of a metal/metal oxide/ZrO.sub.2 sensor and a noble metal sensor in a combination wherein the outer sheath of a mineral insulated cable acts as the conductor for the noble metal and the central conductor of the MI cable acts as the conductor for the metal/metal oxide/ZrO.sub.2. The metal/metal oxide/ZrO.sub.2 sensor acts as a reference electrode in the BWR environment (i.e., at constant pH) and the noble metal sensor acts as a hydrogen electrode which responds to the dissolved hydrogen content in the BWR water.

    摘要： Electrochemical corrosion potential (ECP) probe assemblies may be used to monitor ECP of materials due to coolant chemistry in an operating nuclear reactor. Example embodiment assemblies include at least one ECP probe that detects ECP of potentially several different materials, a structural body providing a fluid flow path for the coolant over the ECP probes, and a signal transmitter that transmits or carries ECP data to an external receiver. The ECP probes may be of any number and/or type, so as to detect ECP for different component materials, including stainless steel, a zirconium alloys, etc. The ECP probes may further detect ECP due to ion concentration, pH, etc. The ECP data may be transmitted through wired or wireless signal transmitters. Example methods include installing and using example embodiment ECP probe assemblies in nuclear reactors and facilities.

    摘要： A method of monitoring process parameters and process effectiveness over a global network enables multiple processing sites to utilize globally compiled field data to determine process parameters and the like. Application parameters are received from multiple processing sites over the global network, and post-application data is received from the multiple processing sites at preset time intervals. The application parameters and the post-application data are analyzed to determine analytical models for future application parameters, which are accessible by system users via the global network.
