Chemistry probe assemblies and methods of using the same in nuclear reactors

A method of installing an electrochemical corrosion potential (ECP) probe assembly in a nuclear reactor, the method comprising:

• securing an ECP probe assembly in a desired orientation and location inside of a reactor pressure vessel of the nuclear reactor, the ECP probe assembly including,
• a plurality of ECP probes separate from each other within the ECP probe assembly and each configured to detect ECP of different component materials when a coolant in the nuclear reactor contacts the plurality of ECP probes,
• a structural body housing the plurality of ECP probes and providing a coolant flow path so that the coolant flows through the assembly and contacts the plurality of ECP probes, and
• at least one signal transmission medium configured to transmit the ECP of the coolant from the plurality of ECP probes;
• and
• communicatively connecting the plurality of ECP probes to a receiver outside of the reactor pressure vessel,
• wherein a first ECP probe of the plurality of ECP probes and a second ECP probe of the plurality of ECP probes are configured to detect the ECP for the different component materials, and wherein the different component materials include stainless steel and a zirconium alloy.

A method of installing an electrochemical corrosion potential (ECF) probe assembly in a nuclear facility, the method comprising:

• securing an ECP probe assembly in a desired location in the nuclear facility, the ECP probe assembly including,
• a plurality of ECP probes separate from each other within the ECP probe assembly and each configured to detect ECP of different component materials when a fluid in the facility contacts the plurality of ECP probes,
• a structural body housing the plurality of ECP probes and providing a fluid flow path so that the fluid flows through the assembly and contacts the plurality of ECP probes, and
• at least one signal transmission medium configured to transmit the ECP of the fluid from the plurality of ECP probes;
• and
• communicatively connecting the plurality of ECP probes to a receiver in a second location in the nuclear facility,
• wherein a first ECP probe of the plurality of ECP probes and a second ECP probe of the plurality of ECP probes are configured to detect the ECP for the different component materials, and wherein the different component materials include stainless steel and a zirconium alloy.
