2013年1月1日 · An ECP value of less than -230 mV (vs. standard hydrogen electrode, or SHE) is required to achieve IGSCC mitigation. More than 50 BWRs worldwide have monitored ECP …

2012年1月1日 · Due to extensive stress corrosion cracking (SCC) problems in BWRs, in-plant electrochemical corrosion potential (ECP) monitoring was first developed for BWRs and SCC …

2009年10月15日 · ECP measurements in BWR plants, which are BWR-3 and BWR-4, were performed in Normal Water Chemistry (NWC), Hydrogen Water Chemistry (HWC) and post …

Since HWC + noble metal catalyst is effective at reducing ECP and mitigating IGSCC, it is reasonable to assume that a similar effect on F. en. exists For C&LAS, assuming surface DO …

ECP measurements in the vessel and reactor recirculation loop showed excellent response during and after OLNC applications. ECP decreased below -230 mV(SHE) at which IGSCC is …

Describe the construction of the ECP probe(s) including the electrodes. Explain how ECP is measured and the effect of platinum electrodes such as those shown in Figure 2-13. Describe …

2012年1月1日 · This chapter focuses on the environmentally assisted cracking (EAC) and, more specifically, the intergranular stress corrosion cracking (IGSCC) of austenitic stainless steels …

2000年3月26日 · This paper describes the theoretical understanding and development of the electrochemical corrosion potential (ECP) predictive model to calculate the ECP of structural …

Source term management and dose rate reduction strategies at the GE-designed BWRs operating today have evolved over the past several years. This paper reviews the past and current …

coolant in the BWR contains oxidant concentrations that result in high electrochemical corrosion potential (ECP) under normal water chemistry operation. This increases the
