WIPP Update

September 12, 2014

Waste hoist transformer replacement

Cleaning and soot removal activities on the waste hoist and associated components have been completed. One additional repair is necessary before the hoist can be powered, inspected and returned to service.  Employees are currently working to replace the electrical transformer necessary to operate the hoist.  Crews began removal operations for the old transformer this week and will continue to work through the weekend to complete installation of the new unit. Once the new transformer is installed and power has been restored to the hoist, the electrical system will be inspected and system checks will be performed.  After all inspections are successfully completed, the hoist will be returned to service and workers can conduct a shaft inspection to ensure it is safe for transporting personnel and equipment into the underground facility. Assuming no other maintenance is required, the waste hoist could be returned to service by the end of this month.

Availability of the waste hoist will allow WIPP to significantly increase the overall number of employees that can be in the underground facility at one time.  The additional staff permitted in the mine should result in a corresponding increase in the level of effort for underground facility recovery activities. 

Community meeting scheduled

September 18  – The City of Carlsbad and DOE will co-host its Town Hall meeting featuring updates on WIPP recovery activities. The meeting is scheduled for Thursday, September 18, at 5:30 p.m. Location: Carlsbad City Council Chambers, 101 N. Halagueno Street.  Live streaming of the meeting can be seen at http://new.livestream.com/rrv/.

Energy Secretary Moniz
Tours WIPP

"This is really an absolutely core facility for the country … we’ve just got to stay focused on getting this critical facility back in operation for the country, [and] for the community that has been so supportive and so much a partner in what we have done.” --Energy Secretary Ernest Moniz

On August 11-12, 2014, Secretary Moniz visited Carlsbad meeting with Carlsbad residents and WIPP employees. Secretary Moniz toured the WIPP site and commended employees on their efforts to recover WIPP.

Did you know?

Transuranic, or TRU waste began accumulating in the 1940s with the beginning of the nation's nuclear defense program. As early as the 1950s, the National Academy of Sciences recommended deep disposal of long-lived TRU radioactive wastes in geologically stable formations, such as deep salt beds.

About WIPP

The nation's only deep geologic repository for nuclear waste

The U.S. Department of Energy’s (DOE) Waste Isolation Pilot Plant (WIPP) is a deep geologic repository for permanent disposal of a specific type of waste that is the byproduct of the nation's nuclear defense program.

CH and RH WasteWIPP is the nation's only repository for the disposal of nuclear waste known as transuranic, or TRU, waste. It consists of clothing, tools, rags, residues, debris, soil and other items contaminated with small amounts of plutonium and other man-made radioactive elements. Disposal of transuranic waste is critical to the cleanup of Cold War nuclear production sites. Waste from DOE sites around the country is sent to WIPP for permanent disposal.

TRU waste is categorized as "contact-handled" or "remote-handled" based on the amount of radiation dose measured at the surface of the waste container. Contact-handled waste has a radiation dose rate not greater than 200 millirem (mrem) per hour, while remote-handled waste can have a dose rate up to 1,000 rem per hour. About 96 percent of the waste to be disposed at WIPP is contact-handled.

TRU waste is long-lived and has to be isolated to protect public health and the environment. Deep geologic disposal in salt beds was chosen because the salt is free of flowing water, easily mined, impermeable and geologically stable. Salt rock also naturally seals fractures and closes openings.

The WIPP site, located in southeast New Mexico about 26 miles from Carlsbad, was constructed in the 1980s for disposal of defense-generated TRU waste. The underground repository is carved out of a 2,000-foot-thick salt bed formed 250 million years ago. TRU waste is disposed of 2,150-feet underground in rooms mined from the salt bed.

WIPP has been disposing of legacy TRU waste since 1999, cleaning up 22 generator sites nationwide.
