Broad roads in a thin country - infrastructure concessions in Chile
No full textTo increase investment in infrastructure, in the early 1990s Chile's government introduced private capital into the transport infrastructure sector, covering roads and highways, bridges, tunnels, and airports. The chosen mechanism: a concession scheme through which private firms would finance and build a given project and then operate the infrastructure for a set of number of years, recovering their investment by collecting tolls from users. Among the lessons learned from the experience: 1) As much as possible, avoid concessioning roads for which there are convenient alternative freeways nearby. 2) Choose the right variable for awarding a concession. Avoid mechanisms that (by promoting large payments to the state or short-term concession periods) encourage high tolls, and if you choose to award a concession to the firm charging the lowest tolls, place a floor and ceiling on possible bids. The floor is to guarantee the concession's financial viability; the ceiling is to prevent inefficient traffic diversions. Ties at either end should be resolved by a second variable, such as the level of transfers between the state and the firm. 3) Allow downward toll flexibility so that the concessionaire can react to unexpectedly low traffic flows, especially for certain types of vehicles. 4) Pay special attention to the tendering mechanism and to the general incentive structure. There are limits to the pure least-present-value-of-revenue (LPVR) auction, but income guarantees do enhance liquidity. In fact, a minimum-income guarantee through an LPVR auction is an instrument for credit enhancement, not income support. Alternatively, some form of financial innovation should be encouraged to make debt service commitments more flexible. 5) If concessions are tendered by traditional methods and income guarantees will be given, cover only a fraction of the concessionaire's expected income stream, to reduce the state's financial exposure and to improve the incentives to the concessionaire. 6) Make the contracts as complete as possible but allow for later modifications or renegotiations, and include a well-designed dispute resolution mechanism.Banks&Banking Reform,Roads&Highways,Decentralization,International Terrorism&Counterterrorism,Public Sector Economics&Finance,Public Sector Economics&Finance,Roads&Highways,Airports and Air Services,Banks&Banking Reform,Toll Roads
One-step Monte Carlo global homogenization based on RMC code
No full textDue to the limitation of the computers, the conventional homogenization method is based on many assumptions and approximations, and some tough problems such as energy spectrum and boundary condition are faced. To deal with those problems, the Monte Carlo global homogenization is adopted. The Reactor Monte Carlo code RMC is used to study the global homogenization method, and the one-step global homogenization method is proposed. The superimposed mesh geometry is also used to divide the physical models, leading to better geometric flexibility. A set of multigroup homogenization cross sections is online generated for each mesh under the real neutron energy spectrum and boundary condition, the cross sections are adjusted by the superhomogenization method, and no leakage correction is required. During the process of superhomogenization, the author-developed reactor core program NLSP3 is used for global calculation, so the global flux distribution and equivalent homogenization cross sections could be solved simultaneously. Meanwhile, the calculated homogenization cross section could accurately reconstruct the non-homogenization flux distribution and could also be used for fine calculation. This one-step global homogenization method was tested by a PWR assembly and a small reactor model, and the results show the validity. Keywords: global homogenization method, Superhomogenization theory, RMC code, NLSP3 cod

The Reactor Monte Carlo code RMC: The state-of-the-art technologies, advancements, applications, and next
No full textBased on academic research and industrial applications over more than 20 years, the Reactor Monte Carlo code (RMC) developed by the REAL (Reactor Engineering Analysis Laboratory) team at Tsinghua University since 2000 has become a powerful, innovative, and versatile simulation platform for nuclear reactor analysis, shielding simulations, criticality safety calculations, fusion neutronics analysis and beyond. Utilizing collaborative and agile development technology, advanced methods and the most cutting-edge algorithms can be tested and implemented in RMC quickly and efficiently. RMC has been deployed on many world-class supercomputers in China and played an irreplaceable role in the design and analysis of commercial nuclear power plants and newly designed types of advanced nuclear reactors. This paper reviews the state-of-the-art technologies developed in RMC in recent years, such as stochastic and continuous-varying media modeling, advanced transient simulation capability, more accurate energy deposition model, etc. Parallel acceleration on heterogeneous architecture supercomputers and machine learning algorithms would be incorporated in ongoing research and future development plans
Repeatable self-healing bendable concrete
No full textThe self-healing behaviour of cementitious materials has attracted great attention as it mitigates damages inflicted on concrete structures. The repeatability of this self-healing behaviour is considered an important attribute since these concrete structures require self-repair for multiple damages in their service life. The ordinary Portland cement (OPC) based cementitious materials do not have good repeatability in their autogenous healing according to their previous studies. However, reactive magnesia cement (RMC) has shown great potential in their autogenous healing performance. Therefore, it is necessary to investigate the repeatability of autogenous healing in RMC-based cementitious materials. In this paper, a research was carried out to understand the repeatability of self-healing in RMC-based strain-hardening cementitious composites (SHCC). The dog-bone shaped RMC-based SHCC specimens were subjected to four damaging-healing cycles. They were loaded to 0.5% tensile strain before undergoing the autogenous healing process. The healing regime included submerging of the specimens into room temperature water for one day and drying the wet specimens at laboratory ambient environment for another day. A total of 10 such wetting and drying cycles were applied. The cracks generated during the tensile preloading were analysed before and after the healing process. The resonant frequency (RF) of the specimens was measured after each wetting and drying cycle. The same procedure was carried for some OPC-based SHCC specimens to allow comparison of the two. The results showed that the RMC-based SHCC specimens demonstrated much better repeatability in their self-healing behaviour when compared to that of the OPC-based SHCC specimens. The normalised RF of the RMC-based SHCC specimens were able to recover and even reach more than 100% after several damaging-healing cycles. On the other hand, the normalised RF of the OPC-based SHCC specimens were only able to reach around or even less than 80% after their damaging-healing cycles. It was also observed that the cracks of the RMC-based SHCC specimens generated during the four damaging-healing cycles were distributed evenly along the specimens’ lengths. However, the cracks of the OPC-based SHCC specimens generated during the second and third damaging-healing cycles were mostly at the locations of the cracks from the first damaging-healing cycle. With the information put together, it can be interpreted that the self-healing in the RMC-based SHCC specimens were much more robust and repeatable.Bachelor of Engineering (Civil
Defect structure in yttrium, niobium and lead substituted bismuth oxide solid electrolytes
No full textPhDBismuth oxide based electrolytes are well known for their high oxide ion conductivity at intermediate temperatures (300-700C). Indeed, the defect fluorite structured -phase of Bi2O3 shows the highest known oxide ion conductivity of any material. Unfortunately this phase is only stable above 730C and much research has been carried out on stabilising this phase to lower temperatures through solid solution formation with other oxides. The work described in this thesis examines the structure-conductivity relationships in several substituted bismuth oxide systems. The effects of Nb5+, Y3+ and Pb2+ substitutions for Bi3+ have been examined using a combination of neutron and X-ray diffraction. Conductivity measurements have been performed on selected compounds using a. c. impedance spectroscopy.
Nb5+ substituted systems show extensive superlattice ordering of the fluorite subcell. Three structural types have been examined in the Bi2O3-Nb2O5 binary oxide system, the Type II (incommensurately modulated) structure, the Type III (commensurately modulated) tetragonal structure and the Type IV (Aurivillius) layered structure. The relationship between these structures and that of fluorite is discussed. A detailed investigation of the highly conducting phase -Bi3YO6 was carried out using total neutron scattering methods. The average structure shows oxide ions disordered on the crystallographic scale and distributed over 3 crystallographic sites in the Fm-3m cubic cell. Evidence from the total neutron scattering analysis reveals further detail on local ordering and has provided the first physical evidence of vacancy ordering in a substituted bismuth oxide based fluorite. Double substitution in Bi2O3 has been examined in the systems Bi2O3-Nb2O5-Y2O3 and Bi2O3-PbO-Y2O3. In the Pb2+/Y3+ substituted system, three temperature regions were evident in the Arrhenius plots of total conductivity and were reflected in the thermal expansion of the cubic lattice parameter. The difference between these regions is less pronounced in the Bi2O3-Nb2O5-Y2O3 system with essentially two linear regions identified and an intermediate temperature region. Subtle redistributions of oxide ions are believed to be associated with these transitions. New phases have been examined in the Bi2O3-PbO system and initial structural characterisation of the high temperature phases at compositions Bi3PbO5.5 and Bi4PbO7 has been carried out.S.T.F.C. forly CCLRC studentship gran
Working Paper 55 - Strategic Considerations for Building a Healthy Pipeline for Bank Group Operations
No full textThe African Development Bank has, since 1982, experienced a problem withbunching of projects towards the fourth quarter of each year’s Lending Program.Contributing factors include both systemic and endogenous constraints as well asexogenous constraints. This paper proposes a holistic approach, that recognizesall the forces at work in the development of Public Investment Programs (PIPs) atthe RMC level as well as the Bank’s internal processes that help to guide andgenerate the pipeline.At the RMC level, the paper examines the need to build the capacity of NationalPlanning Commissions (NPCs) to administer the PIP process. It also advocatesfor sensitizing RMCs, through intensive and persistent dialogue, to decentralize thePIP process in order to minimize the risk of marginalizing the poor and vulnerablegroups of society in the PIP process.At the Bank Group level, the paper examines the existing processes for bothlending and non-lending services and explores areas where the Bank’s lendingoperations need to be streamlined to enhance efficiency and cost-effectiveness.To this end, the need to promote and reward good Economic and Sector Work(ESW) is highlighted along with the need to formalize Country Teams and strengthentheir roles. Furthermore, the concept of a Task Manager (TM) is re-examined andproposals are made that will assure greater responsibility and accountability ofTMs and allow them to play a leadership role in building up the Bank’s pipeline. Amore objective and easily monitorable classification of “bankable” projects isproposed along with a more flexible set of lending instruments that are necessaryto secure a smoother implementation of the Bank’s pipeline beyond the three-yearplanning horizon engendered by the three-year lending cycle.
The Development of Neutron Radiography and Tomography on a SLOWPOKE-2 Reactor
No full textAbstractDevelopment of neutron radiography at the Royal Military College of Canada (RMC) started by trying to interest the Royal Canadian Air Force (RCAF) in this new non-destructive testing (NDT) technique. A Californium-252 based device was ordered and then installed at RMC for development of applicable techniques for aircraft by the first author. A second and transportable device was then designed, modified and used in trials at RCAF Bases and other locations for one year. This activity was the only foreign loan of the U.S. Californium Loan Program. Around this time, SLOWPOKE-2 reactors were being installed at four Canadian universities, while a new science and engineering building was being built at RMC. A reactor pool was incorporated and efforts to procure a reactor succeeded a decade later with a SLOWPOKE-2 reactor being installed at RMC. The only modification by the vendor for RMC was a thermal column replacing an irradiation site inside the reactor container for a later installation of a neutron beam tube (NBT). Development of a working NBT took several years, starting with the second author. A demonstration of the actual worth of neutron radiography took place with a CF-18 Hornet aircraft being neutron and X-radiographed at McClellan Air Force Base, Sacramento, CA. This inspection was followed by one of the rudders that had indications of water ingress being radiographed successfully at RMC just after the NBT became functional. The next step was to develop a neutron radioscopy system (NRS), initially employing film and then digital imaging, and is in use today for all flight control surfaces (FCS). With the third author, a technique capable of removing water from affected FCS was developed at RMC. Heating equipment and a vacuum system were utilized to carefully remove the water. This technique was proven using a sequence of near real time neutron images obtained during the drying process. The results of the drying process were correlated with a relative humidity gauge and an NDT technique that could be performed at Canadian Forces (CF) Bases was developed. In order to determine the structural integrity of the component having undergone this water removal, further research was required into the effect of water inside composite honeycomb structures. This need has led to the present development of neutron tomography on the reactor at RMC, which is capable of determining the exact location of water ingress inside composite components. This technique has been successfully applied to coupons as well as to complete rudders
