On the use of the BMC to resolve Bayesian inference with nuisance parameters
Authors: Privas Edwin , De Saint Jean Cyrille , Noguere Gilles
Published: November 2018

Nuclear data are widely used in many research fields. In particular, neutron-induced reaction cross sections play a major role in safety and criticality assessment of nuclear technology for existing power reactors and future nuclear systems as in Generation IV. Because both stochastic and deterministic codes are becoming very efficient and accurate with limited bias, nuclear data remain the main uncertainty sources. A worldwide effort is done to make improvement on nuclear data knowledge thanks to new experiments and new adjustment methods in the evaluation processes. This paper gives an overview of the evaluation processes used for nuclear data at CEA. After giving Bayesian inference and associated methods used in the CONRAD code [P. Archier et al., Nucl. Data Sheets 118, 488 (2014)], a focus on systematic uncertainties will be given. This last can be deal by using marginalization methods during the analysis of differential measurements as well as integral experiments. They have to be taken into account properly in order to give well-estimated uncertainties on adjusted model parameters or multigroup cross sections. In order to give a reference method, a new stochastic approach is presented, enabling marginalization of nuisance parameters (background, normalization...). It can be seen as a validation tool, but also as a general framework that can be used with any given distribution. An analytic example based on a fictitious experiment is presented to show the good ad-equations between the stochastic and deterministic methods. Advantages of such stochastic method are meanwhile moderated by the time required, limiting it's application for large evaluation cases. Faster calculation can be foreseen with nuclear model implemented in the CONRAD code or using bias technique. The paper ends with perspectives about new problematic and time optimization.
Nuclear data uncertainty analysis for the Po-210 production in MYRRHA
Authors: Fiorito Luca , Stankovskiy Alexey , Hernandez-Solis Augusto , Van den Eynde Gert , Žerovnik Gasper
Published: November 2018

MYRRHA is a multi-purpose research reactor able to operate in sub-critical and critical modes and currently in the design phase at SCK•CEN. The choice of LBE was driven by its chemical stability, low melting temperature, high boiling point, low chemical reactivity with water and air and a good neutronic performance. As a drawback, the neutron capture in 209Bi results in the production of 210Po, a highly radiotoxic alpha emitter with relatively short half-life (≈138 days). The 210Po production represents a major safety concern that has to be addressed for the reactor licensing. In this work we used the ALEPH-2 burnup code to accurately calculate the 210Po production in a MYRRHA operating cycle. The impact of using different nuclear data libraries was evaluated and the reliability of the results was determined by quantifying the uncertainty of the 210Po concentration. The uncertainty quantification was carried out sampling the currently available nuclear data covariance matrices with the SANDY code. Also, estimates of the sensitivity profiles were obtained with a linear regression approach. The activation yield of the 209Bi neutron capture reaction was assessed as the largest nuclear data source of uncertainty, however the lack of covariances for such data represent a capital drawback for the 210Po content prediction.
Choice of positive distribution law for nuclear data
Authors: Lahaye Sébastien
Published: November 2018

Nuclear data evaluation files in the ENDF6 format provide mean values and associated uncertainties for physical quantities relevant in nuclear physics. Uncertainties are denoted as Δ in the format description, and are commonly understood as standard deviations. Uncertainties can be completed by covariance matrices. The evaluations do not provide any indication on the probability density function to be used when sampling. Three constraints must be observed: the mean value, the standard deviation and the positivity of the physical quantity. MENDEL code generally uses positively truncated Gaussian distribution laws for small relative standard deviations and a lognormal law for larger uncertainty levels (>50%). Indeed, the use of truncated Gaussian laws can modify the mean and standard deviation value. In this paper, we will make explicit the error in the mean value and the standard deviation when using different types of distribution laws. We also employ the principle of maximum entropy as a criterion to choose among the truncated Gaussian, the fitted Gaussian and the lognormal distribution. Remarkably, the difference in terms of entropy between the candidate distribution laws is a function of the relative standard deviation only. The obtained results provide therefore general guidance for the choice among these distributions.

Authors: Liu Xuehua , Ding Liping , Li Yanfeng , Chen Guangxuan , Du Jin
Published: November 2018

Register pressure problem has been a known problem for compiler because of the mismatch between the infinite number of pseudo registers and the finite number of hard registers. Too heavy register pressure may results in register spilling and then leads to performance degradation. There are a lot of optimizations, especially loop optimizations suffer from register spilling in compiler. In order to fight register pressure and therefore improve the effectiveness of compiler, this research takes the register pressure into account to improve loop unrolling optimization during the transformation process. In addition, a register pressure aware transformation is able to reduce the performance overhead of some fine-grained randomization transformations which can be used to defend against ROP attacks. Experiments showed a peak improvement of about 3.6% and an average improvement of about 1% for SPEC CPU 2006 benchmarks and a peak improvement of about 3% and an average improvement of about 1% for the LINPACK benchmark.

Authors: Lu Jing , Fu Gaosheng , Ren Zhimeng , Liu Jie , Hao Huan
Published: November 2018

The thermal deformation microstructure of continuous extrusion copper bus bar was observed and analyzed in the temperature range from 200°C to 700°C and at strain rate from 0.01s-1 to 10.0s-1 and at deformation amount from30% to 90% on Gleeble1500 test machine. The experiment results show that the higher the temperature, the lower the strain rate, the more dynamic recrystallization occurred. At the same strain rate, the copper bus bar changes from raw material of as-cast organization to recrystallization grain gradually as the deformation temperature and deformation degree increase, and the recrystallization grain size grows older with the rise of temperature. At the same deformation temperature, the temperature of recrystallization nucleation decreases while the strain rate increases. At low strain rate (0.01~1.0s-1), the dynamic recrystallization occurred at 500°C. While at high strain rate (10.0s-1), the recrystallization nucleation is advanced and it is already completed at 500°C. The Z parameters can be used to express the effect of deformation temperature and strain rate on the average grain size D, and the prediction model of the thermal deformation microstructure is obtained as follows: lnD=4.822-0.018lnZ

Published: November 2018

The 30 September 2009 Padang Pariaman (or West Sumatera Earthquake) (M = 7.6 USGS) has caused severe damages of buildings and infrastructures and fatalities. Many of the buildings failed may be due to the low quality of the structures or due to that most buildings were designed Indonesian code SNI 1726-2002, and many of them failed because of the occurrence of liquefaction causing foundation failures. However, a future earthquake could have been even more severe and causes a tsunami, a reality which we shall consider, especially because Padang City is located facing directly to the ocean. Based on the occurrence and experience in Banda Aceh, Padang City has similar risk and yet very limited barrier and lack of evacuation system. For evaluation of this issue, a team of Universitas Katolik Parahyangan conducted a preliminary study on the condition of Padang City and discuss some alternatives to be considered by the government or authority. Methods of research are based on a literature study and collected data for analysis. Options are discussed and conclusions are derived. This paper discusses the important lessons from Banda Aceh failures related to the tsunami, and method to reduce the disaster risk for Padang City by Tsunami Seawall. The purpose of this study is to discuss the risk of the tsunami at Padang City, the preparedness and local condition, and alternative actions to be carried out. There has been pro and cons for Seawall, but the study concluded that due to the fact that tsunami would reach the city within 15-30 minutes after the earthquake and condition of low lying elevation of the Padang City, the use of Seawall for city safety is worth to be considered.

Published: November 2018

Mount Bromo is one of the most active volcanoes in East Java with a 4-5 year interval of the eruption. Its last eruption was in 2015 and is expected to erupt in 2020. The mountain is characterized as having the phreatic type of eruption, which can take months, and made Sukapura district the most seriously affected. Sukapura District is inhabited by Tengger people who strongly uphold their customs. The strong spiritual relationship between Tengger people and Mount Bromo affects the efforts to reduce the disaster risk. In anticipation of the coming eruption in 2020, a disaster risk calculation is required as the basis for disaster risk reduction. This paper examines the risks of Mount Bromo eruption disaster from the aspects of its hazards, vulnerability and community capacity. The results of risk calculation indicate that the vulnerability and capacity are the most influential aspects to the magnitude of the risks suffered by the community. The high-risk areas to prioritize are Ngadisari, Sariwani, Sapikerep, Wonokerto, Ngadirejo, and part of Jetak Village. Moderate risks include part of Kedasih village, part of Pakel Village, part of Ngadas Village, part of Jetak Village and part of Wonokerto Village. The low-risk areas include part of Ngepung Village, Sukapura Village, part of Ngadas Village and part of Wonotoro Village.

It does not focus on the collaborative management model in the subdivision of one organization. The authors’ review based on a disaster event or relevant activities. The result shows that most of the collaborative management in this approach work with state level, representative of the international organization located in the affected country and international level. Less of the case that society gets involved. Some case they work with the military in term of logistics that outstanding case. This approach can explain by the umbrella’s model of Proulx et al. (2014) that all actors make strategic direction and operate under an umbrella organization. The importance of obstacles is communication and networking.

Meteorological hazard has been frequently occurred in Indonesia due to torrential rains. It is important to examine the characteristics of the atmosphere during rainy seasons for hazard mitigation. National Laboratory of Weather Modification Technology has conducted a short Intensive Observation Program (IOP) from January 18th to February 16th, 2016 to collect meteorological data in the vicinity of Jakarta Region. During that period several instruments have been used, such as Radar, Microwave Profiling Radiometer, Automatic Weather Station, and Radiosonde. This paper examines the comparison of atmospheric parameters obtained from Radiosonde and Profiling Radiometer during extreme weather days. The results showed that there were significant differences of instability indices of Radiosonde and Profiling Radiometer data: 15 points for KI, 6 points for TT and 100 points for SWEAT. The atmospheric stability indices of the Profiling Radiometer tended to be lower than Radiosonde. A radar image showing a rainstorm as well as rain rate information validates atmospheric index stability data. Radar and atmospheric instability indices data integration can be used as one of the parameters to forecast extreme weather events and as an early warning system of hazard mitigation.

This study aims to describe the effectiveness of external communication on the Regional Disaster Management Agency at Padang city (BPBD) in Implementing of Tsunami Early Warning System. The organization external communication’s problem in implementing tsunami early warning system became the background of the study. The lack of public understanding about tsunami early warning, unorderly in the evacuation, the reluctance in using the shelter as the evacuate place and the decreases number and quality of communication media in implementing tsunami early warning system by BPBD. This descriptive research is using a quantitative method in which the population is the people residing in the tsunami hazard zone area. The sample, the cluster random sampling technique is used. The data were collected using a questionnaire and measure with Likert scale and supported by documentation study. The results showed that the effectiveness of external communication on Regional Disaster Management Agency of Padang City in implementing the tsunami early warning system is quite useful. The efficiency of 65.48 is in the range of 60-79.99. There are two ineffective factors. First, the community action (taken from effective communication’s indicator) showed the value is 59 which means the sign is in the range 40-59.9 9. The second is from affect factors of the effective communication with value 59.66 means the indicator is in the range 40-59.9 9.

Indonesia is a disaster-prone region facing multiple hazards. The impact has cost human casualties, injuries, damages to assets, environment and regional development. In order to protect the people and assets, the government has increased the capacity to face and anticipate disaster which is through a multi-hazard early warning system (MHEWS). The academic sector in Indonesia, especially prominent universities such as Institut Teknologi Bandung and Universitas Gajah Mada has contributed positively to the development of MHEWS and the Land Slide Early Warning System. This research aims to examine the role of universities in Indonesia related to the establishment of an MHEWS in Indonesia by answering what are the roles and the challenges. The research methodology is through a desk study and document review of government and organizations reports using qualitative and descriptive analysis. The findings of the research indicate the role of universities in the MHEWS is in line with the concept of tri dharma of universities which research, higher education and outreach. This means the role of universities to conduct research related to early warning systems, higher education through having program studies related to disaster management and outreach the role to train the community, organizations, and government through professional networks. Unfortunately, the involvement of the eastern part of Indonesian universities still needs to increase capacity, awareness, and access in utilizing the MHEWS at the local level.

Litter becomes one serious threat for the coastal area in Indonesia. Those litters are derived from various anthropogenic activities and various land uses. Indonesia is declared as the biggest second country after China in contributing marine debris in 2015. But marine debris in Indonesia, not all derived from the domestic product. In the coastal area of Aceh province, there are marine debris which derived from foreign countries. One right way to overcome the pollution in the coastal area is by incorporating Marine education into the educational curriculum. In anticipating the effect of destruction in the marine environment, Indonesian Ministry of Marine Affairs and Fishery has launched a coastal education model namely Indonesian Coastal Education. The aim of this study is (1) to identify the types of pollution in the coastal area, (2) to arrange the steps of observation, and (3) to arrange the action plan of Indonesian Coastal Education (ICE) in overcoming pollution in the coastal area. This study uses literature study by searching the reference of theories which are relevant to the case or problem of litter/waste pollution in the coastal area. By applying 4A learning method in ICE, students can directly understand the problem occurs in their area, particularly related to litter pollution in the beach. The concept of the study is, students of ICE are expected to be able to arrange an action plan based on the result of observation and analysis.

It had been more than 400 hundred years since Mount Sinabung last eruption. Hence, people have built settlements at its slope. However, in 2010, the mount began to erupt and consequently more than 10.000 ha farmland damaged and more than 28.000 people evacuated. Until now, it has been 7 years since the eruption and no one knows when it stops. Who will help the community when disaster strikes? Based on experience, the fastest aid always comes from the adjacent community. Therefore, the first helper, which are expected, is from the adjacent community or from the victims themselves. This research aims to find the level of capacity of victims of Mt. Sinabung disaster in encountering the disaster at every process of disaster management. This research is a qualitative descriptive research. The data obtained from interviews and focus discussion group (FGD). Interview conducted to get what the community has been done at every phase of management. This study found that rank of the capacity of villagers at every phase of disaster management in general is very low. They only reach the phase of understanding, but not motivated or search much information about prevention, mitigation and response.
