Embodiment Construction

[0035] The measuring device 1 is intended to be arranged in a structure 3 of a nuclear installation which is figure 1 Storage pool 5 for spent fuel assemblies. The structure includes a certain amount of liquid 7 . The volume of liquid is delimited by the bottom 9 and the side walls 11 and has a free surface 13 upwards.

[0036] The measuring device 1 is provided for measuring the liquid level, which corresponds to the height of the liquid considered along the vertical direction from the bottom 9 to the free surface 13 .

[0037] In the case of spent fuel storage ponds, the liquid is usually water.

[0038] The measuring device 1 can be used to measure the liquid level of other structures of the nuclear reactor, such as other pools or vats. It can also be used in structures located in facilities other than nuclear reactors, for example reprocessing facilities for spent fuel assemblies or any other fuel cycle facility.

[0039] The liquid does not have to be water, but can b...

Abstract

The invention relates to a measuring device comprising: at least one optical fibre (15); a light source (17); and an analyser (19) for analysing light radiation back-scattered by the optical fibre (15) and deducing therefrom the liquid level in relation to the bottom (9). The measuring device (1) comprises a floater (21) floating at the free surface (13) of the liquid, the floater (21) comprisinga passage (23) in which the or each optical fibre (15) is received in a sliding manner, a section (25) of the optical fibre (15) engaged in the passage being crimped or diverted.

Description

technical field [0001] The present invention generally relates to level measurement in nuclear installations, and in particular to storage tanks for spent fuel assemblies. [0002] More specifically, according to a first aspect, the invention relates to a device for measuring liquid levels by means of light reflectance gauges for use in structures of nuclear installations containing a quantity of liquid which is supplied from the bottom and free For surface definition, the measuring device consists of: [0003] - at least one optical fiber arranged to be immersed in a liquid through a free surface; [0004] - a light source, which feeds optical radiation into the optical fiber; [0005] - An analyzer arranged to analyze the optical radiation backscattered by the optical fiber and deduce therefrom the level of the liquid relative to the bottom. Background technique [0006] JP2014-41023 describes such a device. The device comprises a measuring well in hydrostatic equilibr...
