WIPP - The Waste Isolation Pilot Plant
What is WIPP?
In 1979, Congress authorized the Department of Energy (DOE) to construct WIPP 26 miles east of Carlsbad, New Mexico. The waste is buried 2,150 ft. beneath the surface in a salt formation. DOE claims that WIPP has been constructed to demonstrate the safe underground disposal of transuranic nuclear weapons waste presently stored at DOE facilities around the US. DOE also maintains the option to dispose of its non-weapons transuranic wastes at WIPP. On March 25, 1999 the first shipment of waste arrived at WIPP from Los Alamos National Laboratory.
The Waste
Transuranic waste (TRU waste) is waste contaminated by elements heavier than uranium (such as plutonium) and which has a level of radioactivity greater than 100 nanocuries per gram for 20 years.
The form of plutonium used in weapons production has a half-life of 24,000 years, meaning that half of the plutonium will have decayed into other elements after 24,000 years. Transuranics are man-made alpha-emitters. Alpha particles are helium nuclei (2 protons) emitted by plutonium radioactive decay. They can be easily stopped by a piece of paper or your skin, but are extremely damaging if inhaled or absorbed by an open wound. Over half of the future WIPP waste is mixed waste - that is radioactive waste mixed with non-radioactive hazardous materials like lead, carbon tetrachloride, etc.
Transuranic waste is classified into two groups, remote-handled and contact-handled. Remote-handled waste is too dangerous for workers to come into direct contact with, so they must use shielding and remote operators to handle the disposal containers. The Department of Energy allows its employees to work directly with contact-handled waste.
Contact-handled transuranic waste is currently disposed of at WIPP. The draft permit will allow for remote-handled waste to be brought to WIPP as well. There are many additional risks associated with this level of waste, including concerns about exposure of the general public when the waste is transported on public roads.
WIPP is often promoted as the solution to the transuranic waste problem. In reality, it is planned to hold only a small percentage of DOE's total existing TRU waste which is contaminating soil and water at various facilities around the country. In fact, much of the waste planned for WIPP has not even been created yet. Instead of being the answer to our waste problem, WIPP is the political solution that enables the production of more waste and therefore a continuation of nuclear weapons research, development and production.
The Site - Theory
In 1956, the National Academy of Sciences (NAS) recommended salt formations as the most promising type of site for permanent underground disposal of radioactive waste because salt tens to creep. It was assumed that the salt would collapse around the waste, creating a naturally sealed tomb that would prevent the waste from moving. Also, it was assumed that any underground salt formation would be dry.
The Site - Reality
Almost immediately, scientists discovered the WIPP did not fulfill the ideal. During excavation, fractures appeared, creating new pathways for the release of waste to the environment. Also, the salt was not dry, but contained water which was seeping into the underground rooms. Additional water was coming down the shafts and a pressurized brine reservoir was discovered below the site.
All this water creates potential pathways for radioactive releases. In the future, when the water mixes with the waste and the decaying metal drums in which the waste is packed, the radioactive slurry will migrate through the cracks and fissures in the salt. Because there are large amounts of potash, natural gas and oil near the site the repository may be breached by the future drilling activities of people looking for these resources. Radioactive materials could travel to the surface through the boreholes. If the brine reservoir below the repository is also breached, the pressurized brine will push the radioactive slurry to the surface with even greater force.
There are many other problems with both the waste and the site. The decay of the nuclear waste and the decomposition of the drums in which it is packed creates flammable gases. The waste is also wrapped in plastic bags which can create a static electrical spark. During operations, this combination of flammable gases and electrostatic plastic bags could create a spontaneous fire or explosion at the facility or when the waste is moved. Also, the amount of gas generated may be enough to keep the rooms from closing around the waste as planned. And, because the hydrology around the site is not fully understood, there are serious questions about how long it would take contamination from the project to reach the nearby Pecos River. Current estimates range anywhere from less than 100 years to 14,000 years or more. Finally, DOE has not solved the problem of sealing the shafts leading into the repository. There is currently no proven technology to seal shafts in salt formations.

Transportation
DOE predicts the most serious and widespread public exposure to radioactive materials from WIPP will result from transportation. Over 38,000 shipments through New Mexico are expected during the facility's operational lifetime of 35 years. Waste will travel through 22 states and 14 Indian reservations. DOE expects there will be a number of accidents that will release radiation.
The shipping container for the waste (the TRUPACT II) has only been tested to out-of-date standards and has not been demonstrated to withstand a crushing accident. Many of the chemicals that are routinely transported on the roads today burn at temperatures twice as high as the testing temperatures used to approve the container. In the case of an accident in New Mexico, it would take 1-5 hours before special DOE Radiological Assistance Teams could reach the wreck.
WIPP waste contains alpha, beta, and gamma radiation. However, gamma radiation will pass through the walls of the TRUPACT IIs during normal operations, potentially exposing to radiation anyone living on the WIPP routes or driving near one of the trucks. Gamma radiation is electromagnetic radiation of high photon energy (X-rays, for example, are the lowest energy gamma rays). Gamma rays are highly penetrating and will often pass right through the body, sometimes without doing damage. They can be stopped by several inches of lead or several feet of concrete (neither of which the TRUPACT IIs have). Examples of gamma ray-emitting elements are americium (a decay product of plutonium) and cesium.
Economics
The perception of radioactive contamination can affect tourism and create a negative market for any agricultural products that are perceived to be contaminated. There are at least however many trucks per day carrying radioactive materials through New Mexico to and from Los Alamos National Laboratory and WIPP. If WIPP (and the proposed Yucca Mountain high-level waste repository in Nevada) are allowed to open, the transportation of radioactive materials through our state will rise dramatically.
Today it is virtually impossible to obtain homeowners insurance against radioactive contamination. If your home, business or ranch were to be contaminated, either through normal WIPP operations or through an accident, the government would decide if cleanup of the contamination were economically feasible. You would have to prove government liability at your own expense and might never be compensated for contaminated products, crops, the cost of cleanup or your property.
Real estate values along the WIPP route have been shown to decline even before any waste has been transported to WIPP. Again, even the perception of possible contamination is enough to potentially affect business. Investor interest in New Mexico may drop and bond ratings may fall as the risk of contamination becomes well known.
