| 20090118560 | Nuclear waste removal system and method using wet oxidation - Methods for removing nuclear waste from a component are provided. In one embodiment, the method includes the steps of supplying oxalic acid to the nuclear waste on the component to form an oxalic acid/waste solution, feeding the oxalic acid/waste solution from the component, feeding an oxidant to the oxalic acid/waste solution to form carbon-dioxide, water and a precipitate, and separating the precipitate from the water. A system for removing nuclear waste is also provided. | 05-07-2009 |
| 20110120497 | CORROSION PRODUCT CHEMICAL DISSOLUTION PROCESS - A method for removing corrosion products from a system, the method including: adjusting the system temperature to between 115° F. to 212° F.; injecting a cleaning dissolution solvent into the system; injecting a gas into the system after the system is filled with the cleaning dissolution solvent; the gas mixing with the solvent in the system; draining the solvent from the system after a predetermined period of time of dissolution; injecting a passivation composition into the system; injecting a gas into the system, the gas mixing the passivation composition; draining the system of the composition after a predetermined period of time of passivation; rinsing the system with a low volume solution; and rinsing the system at with a full volume solution. | 05-26-2011 |

| 20090173293 | Injection of premixed concentrated chemical solution in steam generator chemical cleaning - A steam generator chemical cleaning system is provided wherein a concentrated chemical cleaning solution is premixed off-site in sufficient volume and concentration to allow the dilution to proper cleaning level be achieved by slow injection into the generator when filled with demineralized water. The premixed chemicals are transported in a tanker to the generator site and injected therein directly from the tanker. | 07-09-2009 |
| 20090183694 | System and method for crevice cleaning in steam generators - A method is provided for cleaning crevices between a plurality of tubes and a plurality of tube support plates supporting the tubes in a steam generator. The steps include filling a secondary side of the steam generator with a solvent to a first level above a first tube support plate to be cleaned, draining the solvent to a second level lower than the first tube support plate, and refilling the secondary side of the steam generator with the solvent to a third level above the first tube support plate. A cleaning system is also provided. | 07-23-2009 |

| 20090267362 | TAMPER INDICATING ENGAGEMENT LOCK FOR A CONTAINER - A lock includes first and second mating members. The first member is an elongate member with a first and second ends. The first end has a first transverse dimension and is provided with a plurality of first anti-rotational elements. The second end defines a head with a second transverse dimension greater than the first transverse dimension. The second member has a cavity configured to receive the first end of the first member. The cavity is provided with a plurality of second anti-rotational elements that engage and lock with the first anti-rotational elements when the first end of the first member is inserted into the cavity. | 10-29-2009 |
