IAEA Update: Filling in the Resource Gaps The Role of Technical and Scientific Support Organizations

Filling in the Resource Gaps

The Role of Technical and Scientific Support Organizations

Regulation of Ph solution - Courtesy of IRSN
The rapid expansion of nuclear and radiation-related activities in many States has highlighted the limited number of available skilled and experienced experts. Nuclear safety considerations in these countries make a qualified workforce mandatory. Nuclear security considerations and other drivers add to this need. For many organizations and institutions, expertise and resources necessary to sustaining nuclear and radiation safety and security are in very short supply. Technical and Scientific Support Organizations (TSOs) help fill these resource gaps.
TSOs comprise of competent, long-standing experts who deliver technical and scientific services to national nuclear regulatory authorities and industry. They also may advise governments to assist them in achieving the highest possible levels of safety and security for nuclear, waste management, radiation protection-independent of external interests.
What Challenges do TSOs Face?
TSOs face many challenges in building and maintaining strategic partnerships to support the expansion or the re-establishment of a nuclear programme in countries with operating nuclear power programmes and in countries embarking on nuclear power for the first time.
TSOs are private sector companies and organizations worldwide whose key role focuses on the design, construction, operation and management of nuclear plants (NPPs). However, they can and do work for both industry and the regulatory body at the same time. Maintaining their independence from owner/operators, regulators and vendors requires them to follow a strict code of ethics so that nuclear safety and security is not comprised by these overlapping relationships.
In embarking countries, TSOs from other countries are often called upon to supply various services and hence, need to be able to cope with the way in which countries nuclear safety regulations differs; TSO's must maintain expertise on nuclear safety even when facing changing requirements from country to country.
How does IAEA support Member States use of TSOs?
IAEA plays a vital part in the national and international efforts made to ensure the effectiveness of nuclear safety and security of regulatory systems. This includes promoting and supporting efforts to maintain and strengthen the actions of TSOs in the enhancement of global safety and security; fostering technical meetings and international conferences specifically aimed at developing and enhancing a common understanding of the responsibilities, needs, functions and opportunities of TSOs; and strengthening international cooperation and networking among TSOs with a view to firm up nuclear and radiation safety and security regulations, including capacity building.
In addition, the IAEA has signed a practical arrangements agreement with IRSN - the Institute for Radiological Protection and Nuclear Safety of France on 27 March 2014, which provides for a cooperation mechanism to obtain alternate radiation safety technical services when needed, such as individual monitoring, calibration and assessment. These practical arrangements extend both organizations' abilities to provide radiation protection services to Member States upon request.
Finally, the IAEA is convening the third TSO conference in Beijing, from 27 to 31 October 2014, which provides an important platform to discuss the challenges faced by the TSOS in providing assistance to regulators and operators with regard to nuclear and radiation safety and security. Specifically, this conference aims to:
  • Discuss the role of research and development in enhancing nuclear safety;
  • Help participants to understand the impact of the 2011 Fukushima Daiichi accident on TSOs and to extract lessons to be learned;
  • Highlight the role of TSOs in the implementation of the IAEA Action Plan on Nuclear Safety;
  • Provide a forum for discussion of the roles, functions and value of TSOs in enhancing nuclear and radiation safety and nuclear security, including through capacity building in those countries launching or expanding their nuclear power programmes;
  • Facilitate the exchange of experience and good practices in planning and implementing cooperative activities for capacity building and in identifying needs for assistance activities from the standpoint of recipient countries;
  • Consider appropriate approaches for enhancing cooperation and effective networking among TSOs and beyond, including centres of excellence;
  • Provide an overview of the technical and scientific support needed for maintaining a sustainable nuclear safety and security system; and
  • Foster continued dialogue on all relevant technical, scientific, organizational and legal aspects at the international level.
More information on this conference can be accessed here.
Regular updates throughout the conference can be viewed on the IAEA's Facebook page and on Twitter using the hashtag #TSObeijing.

ANS Update 10/24 “Nuclear Medicine” – National Nuclear Science Week, Day 5 (October 24)

“Nuclear Medicine” – National Nuclear Science Week, Day 5 (October 24)

NSWlogoThe fifth and last day of Nuclear Science Week is all about Nuclear Medicine.  Have you ever experienced a procedure at a hospital that employed radiation?  Did you know that there are actually many different ways that nuclear technology is employed in medicine – and not just at your local hospitals?
According to our own Center for Nuclear Science and Technology Information,
Nuclear medicine and radiology are the whole of medical techniques that involve radiation or radioactivity to diagnose, treat and prevent disease.  While radiology have been used for close to a century, “nuclear medicine” began approximately 50 years ago.  Today, about one-third of all procedures used in modern hospitals involve radiation or radioactivity.  These procedures are among the best and most effective life-saving tools available, they are safe and painless and don’t require anesthesia, and they are helpful to a broad span of medical specialties, from pediatrics to cardiology to psychiatry.
You can learn much more about nuclear medicine at the dedicated CNSTI page on the topic – click here to access it.
The US Nuclear Regulatory Commission has oversight over some, but not all, medical uses of nuclear material and technology.  To read about NRC’s role and to see what it regulates, click here.
The US Food and Drug Administration regulates a portion of the medical field that uses radioactivity; click here to access the FDA’s extensive site portal covering all aspects of what it regulates.  You can also find many other useful resources at this link.

NRC Blog Update 10/24 NRC Science 101: How a Nuclear Reactor Generates Electricity

NRC Science 101: How a Nuclear Reactor Generates Electricity

Paul Rebstock
Senior Instrumentation and Control Systems Engineer
 
science_101_squeakychalkHow does a nuclear reactor generate electricity? Well — it doesn’t, really. Let’s begin at the end and see how it all fits together.
We begin by looking at an electric motor. A motor consists primarily of two major components: a stator, which stands still, and a rotor, which rotates within the stator. When electricity is applied to the motor, electromagnets within the stator and the rotor push and pull on each other in a way that causes the rotor to rotate. The magnets in the stator pull magnets in the rotor toward them, and then, as the rotor magnets pass by reverse themselves and push the rotor magnets away.
The parts are arranged so the pulling and pushing are all in the same direction, so the rotor spins inside the stator. The electrical energy applied to the motor results in mechanical energy in the rotor.
But that same machine can be used in reverse: If some outside force causes the rotor to spin, the interaction of the magnets causes electricity to be produced: the “motor” is now a “generator,” producing electrical energy as a result of the mechanical energy applied to its rotor. That’s the most common way to make large quantities of electricity.
So how do you make the rotor spin? That’s where the nuclear reactor comes in, although still indirectly. Recall that a nuclear reactor generates heat. The fuel rods get hot because of the nuclear reaction. That heat is used to boil water, and the steam from that boiling water is used to spin the rotor. As we have seen, when the rotor spins, electricity comes out of the stator.
When water boils, the steam that is produced occupies much more physical space than the water that produced it. So if you pump water through some sort of a heat source — like a nuclear reactor, or a coal‑fired boiler — that is hot enough to boil the water, the exiting steam will be travelling much faster than the water going in. That steam runs through a machine called a turbine, which acts something like a highly‑sophisticated windmill. The physical structure is vastly different from a windmill, and a large turbine can be far more powerful than any windmill that has ever been made, but the effect is somewhat the same: the steam, or wind, causes part of the machine to spin, and that spinning part can be connected to a generator to produce electricity.
The steam leaving the turbine is collected in a device called a condenser — essentially a metal box the size of a house, with thousands of pipes running through it. Cool water flows through the pipes, and the steam from the turbine is cooled and condenses back into water. Then the water is pumped back through the heater and the cycle continues.
Now, back to the nuclear reactor . . . We have seen how the reactor generates heat, and we have seen how heat is used to generate steam and how the steam then powers the turbine, which spins the generator that produces electricity. The final piece in the puzzle is how the heat from the nuclear reaction generates the steam.
bwrThe fuel rods are suspended in a water bath contained in a large metal container somewhat like a gigantic pressure cooker. A typical “reactor vessel” might be 15 feet in diameter and 20 feet high, and some are much larger than that. In some types of reactors, the water is allowed to boil, and the heat generated in the fuel rods is carried away in steam. These are called “boiling water reactors” (or “BWR”).
In others, the water is held at a very high pressure — on the order of 2000 pounds per square inch. (By the way, that is more than 60 times the pressure in the tires of a typical car.) In that situation, the water cannot expand and cannot boil. The water in that type of reactor carries the heat away while remaining liquid, and that heat is then transferred to another water system where the boiling occurs. This transfer takes place in a device aptly named a “steam generator.”
These are called “pressurized water reactors” (or “PWR”). A small PWR might have two steam generators. A large one might have four. Some have three. The steam from all of the steam generators is typically combined into a single “main steam line” that carries the steam to the turbine, so the reactor and all of the steam generators act together as a single steam source.
The water from the condenser is pumped directly into the reactor vessel for a BWR, or into the steam generators for a PWR.
So there you have it: the nuclear reaction heats the fuel, the fuel heats the water to make steam, the steam spins the turbine, the turbine turns the generator, and the generator makes electricity.

Stopping a Nuclear Nightmare: How We Can Secure Loose Nuclear Materials

Stopping a Nuclear Nightmare: How We Can Secure Loose Nuclear Materials

10/24/14
Kenneth N. Luongo
Nonproliferation, Nuclear Weapons, Security, United States

"Since the collapse of communism, there have been 664 reported incidents involving the theft or loss of nuclear and other radioactive materials..."

The faltering international response to the Ebola epidemic and the rise of ISIS in the Middle East starkly highlight the need for a modernized global architecture that can effectively address rapidly mutating challenges to the world order. In response to the recent cascade of global instability, President Obama acknowledged that, “to keep pace with an interconnected world . . . we cannot rely on a rule book written for a different century.” He should heed his own advice. The international forum he created to strengthen the security of vulnerable nuclear materials and facilities is heading into its endgame, still relying on twentieth-century rules that leave glaring gaps unaddressed.
The United States will host the fourth and likely final Nuclear Security Summit (NSS) in 2016, and later this month, representatives from over fifty nations will start planning the agenda. They need to overcome the prevailing complacency about the strength of the current security system and its ability to prevent a nuclear nightmare.
The current system suffers from three fundamental weaknesses. It mostly relies on voluntary obligations that nations can take or leave. There are no mandatory international standards that would allow for effective evaluation of security consistency and competency across borders. And, there is no requirement for peer review or even communication among countries about their security strategy and practices. The result is an opaque global patchwork, with the weakest links offering tempting targets for increasingly emboldened terrorists.
U.S. leadership is essential for addressing these problems. The three previous gatherings have yielded important results, in particular the accelerated removal of bomb-grade materials from a variety of countries. But many of the accomplishments plucked low-hanging fruit.
