Abstract The Waste Isolation Pilot Plant (WIPP) is the United State’s (U.S.) first deep disposal facility for transuranic radioactive (TRU) waste generated as a result of defense activities. The U.S. Environmental Protection Agency (USEPA or “the Agency”) initially certified the WIPP in May 1998, and WIPP received the first shipment of TRU waste on March 26, 1999. Every five years thereafter, USEPA is required by law to recertify whether the WIPP continues to comply with the USEPA’s radioactive waste disposal regulations. USEPA is coordinating with the U.S. Department of Energy (USDOE), which operates the WIPP, to prepare for the first recertification in 2004. This process involves many interesting technical and policy issues.

Effective Void Ratio

AbstractBentonite/sand mixture is expected to be an effective component of barriers for radioactive waste disposal facility. Impermeable mixture can be obtained through enrichment of the bentonite content,but it is difficult to estimate a permeability of bentonite/sand mixture before permeability test. At designing of bentonite/sand mixture, we have to decide which sand to be used, and what bentonite content is. But.this means that designing will be a time-consuming task. In this report, we made many kinds of bentonite/sand mixtures using some kinds of sand with different bentonite content, and permeability tests were conducted for these mixtures. After examination of the permeability tests results, the effective void ratio of bentonite/sand mixture which was obtained by compaction test, is an efficient parameter for estimation of the permeability. Last of all, we propose the method of designing bentonite/sand mixture using the effective void ratio.
