March 20, 1981 (UN-lOO-N-15) - Sulfuric acid and rinsewater were spilled inside the 108-N building. The unknown amount of liquid was transferred to the acid tank french drains for neutralization. The transfer line developed a leak and released acid solution to the ground. The affected area was estimated to be less than 4.6 m ... 

N-6 Sulfuric Acid Tank French Drains (5) 93 percent sulfuric acid. French drains surrounding acid tanks for containment of incidental spills. 

Fuel Dissolution. In the American and British plants, LWR fuel pieces typically fall directly from the shear into a dissolver basket, which fits inside the dissolver vessel. A soluble poison such as gadolinium is added to the nitric acid to prevent criticahty. The massive end fittings are sometimes separated from the fuel pieces before the latter enter the dissolver. The French have installed continuous rotary dissolvers in the UP3 and UP2-800 plants at La Hague. The units each consist of a dmm rotating within a geometrically favorable slab tank (13). 

Construction of a subsurface structure that penetrates the water table only a short distance can be an effective LNAPL retention technique. Most underflow structures function in the same way as a surface baffle in an oil water separator or a septic tank. The structure must be carefully installed perpendicular to groundwater flow, and have some arrangement to collect the free-phase LNAPL. Often, a simple French drain (constructed parallel to the retaining wall) leading to a recovery well (with skimmer) is effective. A schematic diagram of a hydraulic underflow structure with a skimming unit is presented in Figure 7.3. 

After graduation, Houdry began work at the family plant but was soon drafted into the French army to serve in World War I. He was seriously wounded at the battle of Juvincourt in 1917 while overseeing the repair of damaged tanks. For his service in the war, he was awarded the croix de guerre. 

Notwithstanding the emphasis placed on tanks by Churchill, Fuller and Liddell Hart, this notable British invention had its limitations. British tanks first went into action on 15 September 1916, only nine months after the trials of the first practical machine, and before the inevitable teething problems had been eliminated. French tanks were developed independently but did not see action for another seven months, and the first two types of chars de combat were inferior to the British Mark I in their ability to cross obstacles. The first German tanks did not appear in action until 1918 and again cross-country performance was poor. The British Mark I was prone to mechanical breakdowns, especially on broken ground, as on the Somme battlefield. 

A number of factors contributed to the Allied defeat. German dive bombers acted as mobile artillery, and the concentrated mass of panzer divisions overwhelmed the widely dispersed French tanks and advanced to the Channel, cutting the Allied armies in two. The British Tank... 

As an example, when the French were retreating during WWH, they destroyed in their country all the bridges, industrial installations, oil storage tanks, all electrical lines including concrete poles, etc. When the Germans retreated from occupied territories they mined not only the objects of strategic importance, but also some churches, castles, palaces, monuments, etc... 

Detonating Red Substance (Fr Corps rouge deto-nanc). It is a reddish-brown, very sensitive explosive substance first found during WWI in the plants manufg TNT, on the walls of various lead vessels, such as nitrators, tanks, pumps, pipes, etc. Similar material was found on the walls of some iron vessels. The fires and explosions in several French TNT plants were presumed to be initiated by that "red substance ... 

A number of explosions in French TNT factories which occurred during 1917-18, in particular the one at Neuville-sur-Saone (1917) which caused the destruction of the whole plant, were presumably due to the decomposition of the products of reaction of metals, such as lead or iron, with TNT under the conditions described in a paper by Kovache and Thibon [31]. Products readily decomposed, and sensitive to friction and impact, were formed in various parts of the plant where contact between these metals and the TNT could occur in the presence of dilute nitric acid, for example in the TNT washing tank and granulators. Similar compounds were found in a nitrator where part of the TNT in close contact with metals was subjected to the action of nitric acid vapours, for example around the seals at the stirrer shaft bearings.
