Investigation on exceptional fuel CRUD samples by using radioactivity ratios of cobalt isotopes

Development of a microfluidic setup to study the corrosion product deposition in accelerated flow regions

“…1 The formation, accumulation and release of these corrosion products from internal structural surfaces can cause issues within the primary circuit of a pressurised water reactor (PWR), such as heat transfer reduction from the primary to secondary circuit, 2 an increased radiation field around the primary circuit, 3,4 the axial offset anomaly due to deposition on fuel pins, 5,6 and changing the response of measurement components. 7 Recent works suggest that electrokinetic effects may be a driving force for CRUD deposition in the low conductivity, high purity coolant conditions found in a PWR.…”
