Interaction of Nd(iii) and Cm(iii) with borate in dilute to concentrated alkaline NaCl, MgCl2and CaCl2solutions: solubility and TRLFS studies

“…Waste Isolation Pilot Plant (WIPP), New Mexico, USA) or under consideration. 1 Although exceptionally dry conditions are expected in rock-salt formations, concentrated NaCl and MgCl 2 brines may occur in the unlikely event of water intrusion into the repository. Corrosion of cementitious waste forms in MgCl 2 brines can further lead to CaCl 2 -dominated solutions with pH c r 12.…”
