---|---|---|---|
Short-term lab | 31.8Â mm | JNC (2000) | Uniform corrosion of carbon steel. Base case value |
Short-term lab | 29Â mm | NWGCT (1984) | Conservative corrosion rate, including an allowance for pitting. Base case value |
Natural analogue | 0.09 × 10−3 mm | Weathering of native iron in basalt (Disko Island). These are very low values which may reflect the site complexity. See discussion in Hellmuth (1991a, b) and Miller et al. (2000) | |
