RAD REPORT: Trying to Seal 1,000 Millisieverts of Radiation per Hour Crack: Polymer May Be Helping

Efforts using concrete  to seal the leaking of radioactive water into the Pacific failed , Saturday, April 2,  according to Japanese news agencies. However, Stars & Stripes reported Sunday, April 3, engineers “went farther up the system and injected sawdust, three garbage bags of shredded newspaper and a polymer --- similar to one used to absorb liquid in diapers that can expand 50 times its normal size when combined with water.”

Where has that ingredient been referenced previously? Those in attendance at the March 28 meeting of Huntington City Council watched as a unanimous body approved  a contract for the Huntington Sanitary Board to purchase polymer to absorb water from waste.

According to Stars & Stripes, “the polymer mix in the passageway leading to the pit had not stopped the leak but it also had not leaked out of the crack along with water, so engineers are stirring it in an attempt to get it to expand.”


CNN and other news agencies have confirmed a possible breach in the containment vessel of Reactor 3, which uses the highly volatile and more radioactive recycled plutonium. The NY Times quoted a senior nuclear executive as saying it’s a “large vertical crack” on the side. “The crack runs down below the water…the problem with cracks is they do not get smaller.”

The MOX reactor uses recycled plutonium as its fuel. During the Cold War the United States had several similar reactors, including one at Savannah River. However, plutonium was utilized at the Oak Ride, Paducah and Portsmouth Diffusion plants, and contained in recycled product at the Huntington (WV) Pilot Plant. A former W.R. Grace site (Erwin, Tenn.) performed MOX related work from 1966-1970.

Among the AEC operations at the Erwin, Tennessee site were high and low enriched uranium processes, highly enriched uranium scrap recovery, low enriched uranium recovery, and low enriched uranium scrap recovery.

The document explains that UF4 was weighed into a “reduction batch” and blended with a reducing agent such as magnesium metal. The charge was heated under vacuum in an induction furnace to form uranium metal derby. After cooling the derby was broken and separated from slag. The slag was repackaged for uranium recovery. The uranium derby was “pickled” in acid to remove slag and scale. The pickle solution was sent to scrap recovery of uranium. The pickled derby was then sampled for impurities. Enriched uranium products were packaged for shipment in approved birdcages. (Birdcages were used for storage at the former HPP.)

Although the above comes from a NIOSH document for Erwin, Tenn., it has been stated by former workers that reductions and pickling of materials from diffusion plants occurred at the now buried Huntington Pilot Plant and at one or more other locations in Huntington that received recycled nickel and uranium from the HPP/RPP.

Japanese Energy Secretary Steven Chu stated that about 70 percent of reactor #1’s core has been damaged. Translation: It came close to a full meltdown.

Toyko Electric Power Co. (TEPCO) has found a crack in the pit of Reactor #2 which is generating radiation readings of 1,000 Millisieverts of radiation per hour in the air inside the pit.

A U.N. watchdog has suggested that the evacuation zone be enlarged to 40 km. Those evacuated have been told that they will have to remain away from their homes for an extended period of time.


Japan's Prime Minister Naoto Kan has told the emergency workers that the future of Japan is at stake and they cannot afford to lose the battle.
