In addition to the German competent authority, the Federal Office for Radiation Protection (BfS) , BAM is also the responsible federal authority for testing the package design in certification processes for transport and storage casks used for spent fuel elements and highly radioactive wastes . BAM's tasks as regulated by the Federal Ministry for Traffic, Building and Town Development include mechanical and thermal design safety assessment, the investigation of the safe containment as well as certification of quality assurance measures for production, operation and maintenance.
BAM performs the assessment based on the recommendations of the International Atomic Energy Organization (IAEO) and the relevant national and international legal regulations for the transport of radioactive substances.
The BAM assessment covers mechanical and thermal tests which ensure the safety of a transport container in serious accidents. The sequence of the tests comprise a nine-meter free drop onto an unyielding foundation in various positions selected as most critical to cause maximum package damage, a drop from one meter onto a steel punch onto the most sensitive part of the container followed by a half-hour fire with a flame temperature of 800 °C. The subsequent release of radioactive substances must not exceed a value specified in the dangerous goods transport regulations, and radiation shielding and nuclear safety must be guaranteed. The design assessment is based on tests of prototypes or model containers and/or on calculations or transferability considerations.
For assessing the safety of containers for radioactive substances usually a combination of experimental tests and calculations is used. Additional material and/or component tests may be required. The determination of suitable assessment criteria, e.g. certain strength parameters, are a substantial component of proving a safety concept.
BAM expects justified safety proofs for a new container design by the applicant, especially the proof of mechanical stability with regard to operational and accident conditions. These shall contain a reasonable selection of relevant drop positions with specified goals for individual drop test sequences. For this purpose e.g. preliminary determination of comprehensive and reasonable criteria, verification of suitable calculation models are necessary up to the final comprehensive assessment of container behaviour based on specified assessment of strength analysis criteria.
To ensure that each series of manufactured samples of a tested and certified design reliably fulfils the provisions, BAM specifies and supervises detailed quality assurance measures for the production and operation in both design test and manufacture-linked controls.
The safety testing methods are constantly being developed by BAM based on the latest findings and standards. For test and research purposes BAM has unique drop and fire test facilities, equipment for leakage testing and hard and software for finite element stress analyses which are highly regarded world-wide.Information:

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
