The gamma-spectrometer and procedure for solid radioactive wastes activity and radioisotope structure definition
|
- This work included the development of the normative document “Solid radioactive wastes. The determination of the specific activity and isotopic composition. General provisions”.
This required the examination of more than 30 documents. We had examined the legislative base and the NPP instructions in force relating the solid radioactive wastes radiation characteristics measurements. Additionally we examined actual NPP low and intermediate level radwaste characterization procedures. This made it possible to optimize the radwaste monitoring according Ukrainian normative demands. The document is implemented by NNEGC Energoatom at all Ukrainian NPPs.
- In parallel we had developed an instrument on the basis of scintillation gamma-spectrometer SEG-001m “AKP-S” – SRAW and appropriate measurement procedure.
The procedure was approved by metrological authority. Now these developments are implemented at all Ukrainian NPPs. The implementation included instrumentation production and installation, transfer of the procedures and NPP personnel training in the instruments’ usage, additional consulting. This made it possible to optimize the radwaste monitoring according Ukrainian normative demands. |
