Title

Diamonds (Gem stones - 2).
Objectives

- Extension of INP's gemstones irradiation business.

- To adjust of processing technical diamonds (diamonds which are not of sufficient quality for the jewellery market).

- To create in addition 6 a new workplaces, including 5 workplaces for former weapon scientist employees of INP.
Summary

INP has established processes for colouring gemstones using neutron and gamma irradiations. Under an existing CNCP project they have established commercial contracts for colouring gemstones using neutron irradiation. This project is an extension of INP's gemstones irradiation business.

The throughput of gemstones being coloured by gamma irradiation has been limited by the activity of the Institute's ageing Co-60 source. Following lengthy negotiations, INP have now signed a contract for Mayak to supply them with new Co-60 sources. This will allow them to significantly increase the throughput using gamma irradiation, which is a significant benefit since the turnaround is significantly shorter. Following the success of the CNCP project, INP believes there is an opportunity for processing technical diamonds (diamonds which are not of sufficient quality for the jewellery market). These diamonds tend to be too small or discoloured (brown). Irradiation can significantly reduce the discolouration or change the colour to make the gemstones more attractive to the jewellery market. In particular a jewellery company based in St Petersburg is interested in this process.

The Beneficiary fulfilled its obligations in full and exceeded its obligations in terms of job creation. 7 jobs were created / of which 5 are for the ex-weapon staff, 6/5 jobs were planned initially.

The project is considered to have been completed successfully.

Cost

The DECC's contribution is £ 10,000.
