Project summaryProject objectives
- development of the methods of safety assessment for rail shipments of nuclear materials, such as "fresh" and spent nuclear fuel, sources of ionizing radiation for medicine and industry, etc. and choice of ways for increasing of the safety on the basis of actual Russian railroad accident statistics:
- development of computer database of crashes and accidents, determination of baseline safety level and choice of ways for increasing of safety on the basis of actual Russian railroad accident statistics;
- development of mechanical and thermal (fire) accident models, creation of criteria for hazard of railroad accident proceeding from mechanical and thermal influences on a transported cargo;
- development of the methods of safety assessment for rail shipments of nuclear materials (radioisotopes, spent nuclear fuel, etc.) and working out proposals for increasing of safety level of transportation's.
1. Distribution of recommendations on optimization of routes for trains with nuclear materials on board basing on the risk and cost analysis.
2. Receiving of new criteria of railway accidents on a degree of heaviness of effect on a transported cargo.
3. Distribution of recommendations on the optimal number of escort wagons to provide safety of hazardous cargo transportation as well as their optimal location within a train.
4. Prioritization of nuclear materials safety measures taking into account correlation expenses-risk.
Scientific value of the project:
- preparation and publication of the most complete database on crashes and accidents on Russian railroads.
- creation of risk assessment technique basing on true Russian statistic data on railway accidents.
Team of specialists engaged for the project has all necessary qualifications, experience and skills to solve tasks outlined by the project.
VNIITF specialists have many years of experience in the following areas:
- 10 years of experience in investigation of hazardous materials railway shipments accidents and in putting together and upgrading a database on railway accidents;
- 40 years of experience in solving of mechanical and thermal tasks including analysis of fire situations.
- 10 years of experience in risk assessment.
VNIIZhT specialists have experience in the following areas:
- 40 years of experience in safety issues of railway transportation and investigation of accidents, including accidents with nuclear materials shipments.
Commercial or other value from project implementation
- publication of the most complete statistics data on accidents and crashes on Russian railways;
- creation of risk assessment technique basing on the database of true Russian statistics information on railway accidents;
- introduction of risk assessment methods into the practice of transportation of hazardous industrial cargo.
The project includes following four tasks:
Task 1. The collection, copying, and ordering of information on crashes and accidents from MPS archives. The information should include data on crashes and accidents sufficient in substance and quantity to create physical models and calculate general statistical laws for the occurrence and nature of accidents.
Task 2. The data obtained in stage 1 of the project will make it possible to compute the predicted frequency of accidents for rail transporting nuclear materials, to construct calculated models of a fire and collision of trains, to classify accidents on a degree of heaviness of effect on a transported cargo and to create criteria of danger of transport incident, proceeding from mechanical and thermal effects on a transported cargo.
Task 3. This task includes ascertaining and describing additional technical measures able to increase the level of safety of rail shipments of nuclear materials. The description of each measure under consideration will include the following: definition of the measure:
- general description of the goal the measure is intended to achieve;
- conceptual model for the practical application of the measure;
- a general engineering description of the applicable technical equipment;
- an assessment of the effectiveness of the measure from the standpoint of achievement of the goal,
and a finding regarding conformity to the requirements of the IAEA, Minatom, MPS, and other regulations of the Russian Federation; cost estimates.
Task 4. In this task on the basis of the methods of risk analysis will be developed specific recommendations to improve the level of safety of the nuclear materials transportation on example of transportation of Mayak PO (radioisotopes, fresh and spent nuclear fuel and so on).
Potential role of the US collaborators:
- participating in the stating of the project's tasks;
- organization of both sides visits and seminars on the project's topic;
- participation in preparation of mutual reports and publications.
