DOE selects vitrification, or the incorporation of high-level radioactive waste into glass, as the preferred method for solidifying the waste NFS left at West Valley. The decision to dispose of low-level waste at the WVDP leads to a legal disagreement between DOE and the Coalition on West Valley Nuclear Wastes. Compilation of the EIS is to begin the following year. Solidification of the lower-level radioactive salt solution from the waste tank begins to reduce the amount of highly radioactive glass that will be produced. Waste pretreatment continues until 1995, and results in nearly 20,000 drums filled with radioactive cement.
Radioactive vitrification begins.
The draft Environmental Impact Statement for site closure is released to the public for a six-month review period. The CTF issues its report the following year, stating it finds the site unsuitable for permanent disposal of radioactive waste. Groundbreaking ceremonies for the RHWF are held.
