Neutron exposure and electrochemical corrosion potential

Information available concerning approximate neutron fluence and electrochemical potential for the representative components-of GE, Japanese, Siemens and ABB BWR plants is shown in Table 4-1. 

Plant component Fluence Electro-chemical corrosion potential (Normal Water Chemistry) [mV (SHE)l 

Core Plate - 2.0 xlO [NWC] Lower pleniun 150 Cote plate not measured [HWC] Lower pleniun -400 Core plate -300 

Core Plate (top) 3.6 xlO 2.1 xlO [NWC] Upper Cote about 80 Lower Core about 120 [HWC] Upper Core about -90 Lower Core about -180 

6) Measured at the cleanup line pipe near the RPV (about 1 m) in Gimdreinmingen NPP Unit B [4.2]
