Embodiment Construction
[0071] The following specific embodiments of the present invention in conjunction with the accompanying drawings are further described.
[0072] as Figure 1 As shown, the present invention provides a method for estimating the source of the red oil explosion accident release of the reprocessing plant high discharge liquid evaporator, comprising the following steps:
[0073] Step 100: Estimate the amount of red oil generated in the high-discharge liquid evaporator by:
[0074] According to the following formulas (1), (2) to estimate the amount of red oil produced:
[0075] V red_oil ＝V TBP (1-e -kt Formula (1);
[0076] k＝3.66×10 12 e -14746.2 / T Formula (2);
[0077] Where: V TBP is the amount of TBP that is entrained into the evaporator, L; k is the solution reaction rate, s-1; t is the reaction time, s; T is the high concentration temperature in the waste liquid evaporator, K.
[0078] Step 200: Calculate the energy generated by the red oil explosion by:
[0079] Calculate the expl...

The invention relates to a method for estimating the release source item of a red oil explosion accident in a high-level radioactive waste liquid evaporator in a post-processing plant. The method includes the following steps: estimating the amount of red oil generated in the high-level radioactive waste liquid evaporator; Evaluate the integrity of the high-level waste liquid evaporator; if the high-level waste liquid evaporator is damaged, calculate the initial release amount and the natural evaporation release amount; if the high-level waste liquid evaporator is not damaged, the estimation process ends; The quality of the concentrated solution evaporated instantly: after the evaporator of high-level radioactive waste liquid is broken, all the explosion energy of the red oil is used to evaporate part of the concentrated solution, and the quality of the concentrated solution evaporated at this time is calculated; the quality of the concentrated solution evaporated later: high-level radioactive waste After the liquid evaporator is broken, the leaked concentrated liquid covers the floor of the equipment room, and the mass of the concentrated liquid evaporated on the ground of the equipment room is calculated. According to the method provided by the present invention, the release source item of the red oil explosion accident of the high-level waste liquid evaporator of the reprocessing plant can be quickly obtained.
Description
Technical field [0001] The present invention belongs to the technical field of research on the release source of emergency working conditions in the reprocessing plant, specifically relates to a method for estimating the source of the release of the red oil explosion accident of the high discharge liquid evaporator of the reprocessing plant. Background [0002] When evaporating a solution containing entrained organic solvents and uranium and plutonium metals, the organic solvents and their degradation products will chemically react with the nitric acid solution of uranium and plutonium metals at a certain temperature, resulting in an explosion, that is, "red oil explosion". It is generally believed that "red oil" is a complex compound of nitrified TBP and uranium and plutonium heavy metals, and the main component is nitroso compounds (red is the color of nitroso compounds in diluents). Although evaporator explosions have occurred in foreign reprocessing facilities, the literature...
