4.3. Order of RTG operation background review

61. In the course of preparation for inspection one should get familiar with the results of the analysis carried out by the operating organisation with regard to the information collected during the period of RTG operation. Special attention should be paid to the products located nearby populated sites, especially, if in the course of operation, any unauthorised actions were registered.

If the operating organisation does not have the documentation (complete package or partially) escorting the product to be decommissioned, it is allowed to use other copies of the documents for the given RTG type. In such case the operating organisation drafts and submits the Deed of RTG operational documentation loss.

The analysis of information shall address the following factors:

а) comparison of the values of dose rate generated by RTG, which are measured at the manufacturing plant and during the RTG operation. Special attention should be paid to the products where dose rate increase was noted even if the measured values were within the prescribed limits;

b) estimate of geographical, geo-morphological and climatic characteristics of RTG operation locations (climate, relief, accessibility for unauthorised persons, remoteness from water area, excess, soil etc.) when selecting the decommissioning technology;

c) correct analysis of the hazardous natural events, that may exert impact on the RTG, and the decommissioning process;

d) analysis of RTG technical condition, in particular, notes in logbooks, deeds of shielding container inspection, availability of official reports, notes and memorandums and other evidence of RTG proper operation violations;

e) documentation on the RTG movements from one operational station to another and the reasons for these movements.

62. Analyse the RTG decommissioning program approved by the operating organisation head, paying attention to:

а) administrative an engineering measures, envisaged to ensure the RTG safe decommissioning;

а) adopted to the method of transportation, to radiation and engineering characteristics of the transported freight;

b) agreed on by the territorial body (structural unit of the territorial authority) of the Service which implements state supervision and monitoring at the location of transport organisation.

64. Instructions should allow for the model safety requirements cited in chapter 6 of the present Methodology.

65. Make sure that the air crew and drivers of the transport vehicles used for transportation of radiation packages with RTG (RHS), have the certificates (permits) for hazardous freight class 7 (radioactive substances) transportation, as well as permits for surface transport facilities for transportation of the indicated hazardous freight, drawn up in accordance with the established routine.
