Enhancing Nuclear Plant Economics and Safety through Online Monitoring and Prognostics

Abstract:

The current approach to operations and maintenance (O&M) relies primarily on periodic inspection and maintenance activities scheduled to preclude in-service degradation and failure; however, this approach often leads to unnecessary work and wasted effort. Current trends in the nuclear industry are moving away from these time-based practices toward risk-informed scheduling, based in part on online monitoring of key components. Ongoing research to develop online equipment condition assessment and failure prognostics for active equipment in nuclear power plants helps drive the industry toward more cost-effective O&M. This enhanced situational awareness will be critical for the future fleet of advanced reactors with new concepts of operation.

Hastening Innovation in Materials for Energy

DATE/TIME:

Spring 2019 Colloquium Series
Abstract:
Energy production and availability is the root driving force behind economic development and prosperity.
The energy sector employs 5% of all Americans, with 7% of new job growth attributed directly to energy. Its sustainability and cleanliness drives our largest modern international agreements. It is also one of the largest sources of lost value when things don't go as planned. The reliable production of clean energy comes down to the structural materials used in carbon-free energy production systems. After all, things tend to be made out of materials, and when those materials fail, so do the systems in which they reside. Due to the intense energy flow, regulation, and risk aversion in large-scale, green power production systems, material improvements are difficult to ideate, and even harder to implement at scale.
In this talk, we will discuss the technical causes and solution to two of the biggest problems in geothermal and nuclear energy systems - fouling and radiation damage - which together contribute to the loss of over 0.25% of the GDP of most developed nations. First, a rare geothermal/nuclear utility partnership has resulted in a universal anti-fouling coating design principle, as the conditions found in geothermal wells and nuclear power plants are surprisingly similar. Matching the optical properties of a coating is the key to avoiding fouling in extreme conditions found in large-scale energy production systems. Second, a new type of non-destructive evaluation (NDE) promises to hasten the qualification of nuclear structural materials by a factor of 1,000. This has the potential to reduce the timescale of experiments from years to hours, as we will show in a first-of-a-kind experimental demonstration. Together these results show that rapid innovation is possible in energy systems, provided the problem as posed takes scientific and societal inputs on equal footing.
About the Speaker:

Michael Short joined the faculty in the Department of Nuclear Science and Engineering in July 2013. He brings 15 years of research experience in the field of nuclear materials, microstructural characterization, and alloy development. His group’s research is a mixture of large-scale experiments, micro/nanoscale characterization, and multiphysics modeling & simulation. A core mission of Short's lab is moving into industry in a five-year timeframe, from ideation to implementation. Short’s research focuses on: non-contact, non-destructive measurement of irradiated material properties using transient grating spectroscopy (TGS); preventing the deposition of deleterious phases, such as CRUD in nuclear reactors, as fouling deposits in energy systems; and quantification of radiation damage by stored energy fingerprints. This last project was recently selected for an NSF CAREER award.

Isotopic Feedback and Stability in Fission Waves

Abstract:

Under the right conditions, self sustaining fission waves can form in fertile nuclear materials.  These waves result from the transport and absorption of neutrons and the resulting production of fissile and fissionable isotopes.  When these fission, additional neutrons are produced and the chain reaction propagates until it is poisoned by the buildup of fission products. Fission waves are a form of breed-burn reaction and it is typically assumed that they are soliton-like and self stabilizing in the absence of thermal feedback and unstable when it is present.  However, we show that the situation is more complicated.  In uranium, coupling of the neutron field to the 239U->239Np->239Pu decay chain can lead to a Hopf bifurcation without thermal feedback.  The fission reaction then ramps up and down, along with the wave velocity.  The critical driver for the instability is a delay, caused by the half-life of 239U, between the time evolution of the neutron field and the production of 239Pu. This allows the 239Pu to accumulate and burn out in a self limiting oscillation that is characteristic of a Hopf bifurcation.  In the presence of thermal feedback, the hardness of the neutron spectrum dictates whether the fission wave is stable, unstable, or will undergo a Hopf bifurcation.  Time dependent results are obtained using a numerical implementation of a reduced order reaction-diffusion model for a fast neutron field.  Monte Carlo simulations in combination with a linear stability analysis are used to confirm the results for the full system and to establish the parameter space where the Hopf occurs.

NUCLEAR SCIENCE & TECHNOLOGY’S (NS&T) MODELING AND SIMULATION

DATE/TIME:
MON, 04/01/2019 - 4:00PM TO 5:00PM
LOCATION:
3105 ETCHEVERRY HALL
Spring 2019 Colloquium Series
Abstract:

In 2008, Dr. Martineau’s Laboratory Directed Research and Development (LDRD) project enabled the development of INL’s Multiphysics Object-Oriented Simulation Environment (MOOSE) computational framework. The development of INL’s Multiphysics Object-Oriented Simulation Environment (MOOSE) computational framework has resulted in a multitude of MOOSE-based code efforts funded by Department of Energy (DOE). MOOSE is known for its ability to “cohesively” couple MOOSE-based codes. And recently, through a process known as MOOSE-Wrapped Apps, MOOSE can couple MOOSE-based applications in a “cohesive-like” manner to external (non-MOOSE) or legacy codes. Here, Dr. Martineau will present the MOOSE framework and much of its capabilities with a focus upon multi-physics coupling. He will then describe and show results from several Advanced Reactor Concepts that UCB directly and indirectly plays roles in.

About the Speaker:

Dr. Richard Martineau is currently the Director of Nuclear Science & Technology’s (NS&T) Modeling and Simulation and is responsible for those aspects of developing advanced numerical methods, scientific numerical packages, high-performance computing frameworks, and multi-physics analysis tools for nuclear power applications at the INL. Dr. Martineau has twenty-nine years’ experience conducting numerical methods R&D and computational engineering investigations and his expertise includes computational fluid dynamics, nonlinear coupling methods for multi-physics applications, compressible material dynamics, fluid dynamics and heat transfer theory, and thermodynamics. In 2008, Dr. Martineau’s Laboratory Directed Research and Development (LDRD) project enabled the development of INL’s Multiphysics Object-Oriented Simulation Environment (MOOSE) computational framework. He currently manages the MOOSE team and is PI on RELAP-7, Bighorn, Sockeye, and Pronghorn code efforts.

Disorder-based Instruments and Methods for Sensitive Nuclear Inspections

SPEAKER:
DR. SÉBASTIEN PHILIPPE

STANTON NUCLEAR SECURITY FELLOW

DATE/TIME:
MON, 03/11/2019 - 4:00PM TO 5:00PM
LOCATION:
3105 ETCHEVERRY HALL
Spring 2019 Colloquium Series
Abstract:

Verifying states compliance with international agreements requires trustworthy data.  Acquiring such data requires, in turn, measurement systems that are considered secure by all parties. This is particularly challenging in cases where measurements are conducted in sensitive environments among mutually distrustful parties, for example, as part of verifying compliance with deep nuclear arms-reduction or denuclearization agreements. In this context, measurements on possibly classified items, such as nuclear weapons, are expected to take place during the inspection of military facilities with devices that must be procured in the absence of a trusted-third-party supplier. To address this challenge, this talk introduces “disorder-based” instruments and methods that enable new approaches to the secure inspection of sensitive nuclear activities, sites, and assets, including the possibility for an inspected party to perform minimally intrusive measurements on behalf of inspectors located off-site.

About the Speaker:

Sébastien Philippe is a Stanton Nuclear Security Postdoctoral Fellow at Harvard Kennedy School's Belfer Center for Science and International Affairs. His research interests include nuclear science and cryptography, especially relating to monitoring and verification technologies; and international relations and policy.
