Storage area must prevent direct sunlight to US-05 in a pack. 6 TRANSPORTATION 6.1 US-05 in manufacturer's pack can be transported by any standard means to any distances: - transportation by train must be done in closed clean cars; - if transported in open carriers the packs must be protected by water-proof material; - if transported by air carrier packs must be placed into hermetic warmed area; - if transported by ship packs must be placed into hold. 6.2 The placement of packs must provide steadiness and protection from displacement and impacts. 6.3 The requirements placed on the packing boxes must be met during load and unload. 6.4 Transportation conditions are as follows: - temperature.... from minus 50 to +50 С; - humidity..... up to 98 % at +35 С; - sine vibrations..... in frequency range from 10 to 500 Hz with amplitude 0,35 mm if frequency is lower than crossover frequency, 5,0 g if higher than crossover frequency (group F3 according to GOST 12997-84). 7 UTILIZATION 7.1 At the end of lifetime of US-05 (and all equipment in its package), before sending it to repairs or checking it is necessary to check radioactive pollution of surfaces. Criteria for decontamination are listed in 3.11 ОСПОРБ-99. 7.2 Decontamination must be performed with SAS in case, when level of radioactive pollution can be lowered to acceptable values (table 8.9 НРБ-99, 3.11.3, 3.11.4 ОСПОРБ-99). 7.3 According to 3.7 SPORO-2002 it is allowed to use surface absorbed dose power (0.1m) as criterion for decontamination of product polluted by unknown gamma radionuclides. 6
7.4 In case of excess of dose rate 0,001 mgy/h (1 μsv/h) over background after decontamination or surface radioactive pollution level excess, the product must meet the requirements of radioactive waste (RAW). RAW is a subject for classification according to 3 СПОРО-2002 and decommissioning according to 3.12 СПОРО-2002. 7.5 Product allowed to continue operation after decontamination is a subject for repairs or replacement in case of non-repairability. Non-repairable product without surface radioactive pollution level excess must be disassembled to prevent its operation, and sent to special areas for waste. 7.6 The product with expired lifetime that was allowed for operation after decontamination is a subject for technical examination. In case of satisfactory condition the product is a subject for next lifetime determination. 7
