The titles of all of the volumes are as follows:

Total system performance assessment - 1995: An evaluation of the potential Yucca Mountain repository

“…Since the alloy microstructure is most likely to vary in and around welds, differences in the behaviors are most likely to be with the welded materials (Strum, et al, 1988). The impact of oxidation of the candidate barrier materials in the potential repository condition is considered insignificant (Gdowski and Bullen, 1988).…”

Corrosion models for predictions of performance of high-level radioactive-waste containers

“…oxygen anions diffuse from the solution-film The functional form of Eqs. (11) and (12) interface to the film-metal interface and result in makes it possible to use factorial-designed expercontinuous growth of the oxide film ( Fig. 10).…”

Survey of degradation modes of candidate materials for high-level radioactive-waste disposal containers; Overview

“…Molybdenum is introduced into the austenitic candidates for stabilization of the passive films. Figure 4 shows representative data on corro sion rates of the austenitic alloys-Types 304 and 316 stainless steels and Alloy 825-in rural, urban, and industrial atmospheres [7]. Rates were calculated from weight-loss measurements of coupons after environmental exposure at Baycnne and Newark, New Jersey; Kure Beach, North Carolina; Bridgeport, Connecticut; Point Reyes, Aluminum (wt%) 14 Figure 5 shows representative data on corro sion rates of Types 304 and 316 stainless steels and Alloy 825 in seawatcr (Panama Canal) and in superheated steam (566 and 621°C) [7).…”

“…In Volume 6 [23], Gdowski and Bullen have surveyed the literature (86 articles) on the effect of hydrogen in the candidate materials. Hydrogen can be generated by electrochemical corrosion reactions.…”
