Research onspent resin interface measurement technology based on phase laser ranging
Aiming at the problems such as high failure rate and difficult maintenance,the spent resin interface measuring instru-ment based on phase laser ranging was designed,and the measuring principle,hardware design,software development and perform-ance testing were studied.The study encompassed the measurement principle,hardware design,software development,and perform-ance testing.In this design,the optical fiber split structure is utilized to achieve radiation isolation and create a safety zone.The non-contact laser ranging method is employed to ensure the stability and reliability of the system.A corresponding software algorithm is designed based on the measurement conditions.The system test results demonstrate an accuracy of±10 mm in level measurement and±25 mm in resin interface position measurement within the measuring range of 0~6 m.Analysis reveals that the designed system ex-hibits high detection accuracy in dual-interface measurement for spent resin storage tanks.This provides an effective means for inter-face detection of spent resin in reprocessing plants,contributing significant application value.
