Published: November 2023

AbstractBackgroundMalaria is caused by protozoa of the genus Plasmodium and transmitted by Anopheles mosquitos. In the US, blood donors are assessed for malaria risk, including donor travel or previous residence in endemic areas and history of malaria by questionnaire and deferred for three months or three years, respectively.MethodsThe Procleix Plasmodium Assay is a qualitative nucleic acid test based on transcription‐mediated amplification (TMA) for the detection of 18S ribosomal RNA of P. falciparum, P. ovale, P. vivax, P. malariae, and P. knowlesi for use on the Procleix Panther system. Analytical sensitivity was evaluated with in vitro transcripts and infected red blood cells. For clinical specificity, 12,800 individual donations and 283 pools of 16 samples from routine US donors were screened. Malaria risk was evaluated by testing 862 donors deferred for 3 years. Reactive results were confirmed with in‐house real‐time TMA assay and serology.ResultsAssay sensitivity was 8.47–11.89 RNA copies/mL and 2.10–6.82 infected red cells/mL. Specificity was 99.99% in 12,800 individual donations and 100% in 283 pools of 16. Of 862 tested deferred donor samples, one donor (0.12%) confirmed positive individually and in pools; he remained confirmed positive for 13 months. The infected donor was a prior resident of a malaria‐endemic area in West Africa.ConclusionsThe Procleix Plasmodium Assay showed high sensitivity and specificity and detected Plasmodium RNA in an asymptomatic presenting donor. This assay may prove helpful as a screening test versus the use of risk questions to reduce the number of donors deferred for malaria risk.

Wind energy is a type of renewable energy that has received much attention in the electricity market. This study focuses on forecasting wind speed at Malacca state’s Station. This paper proposes using a Group Method of Data Handling (GMDH) model with a hyperbolic tangent transfer function in forecasting wind speed data in Malacca state. The performance of this model is compared with three other models: Artificial neural network (ANN) hyperbolic tangent, ANN log sigmoid and GMDH model. In addition, this study investigates the impact of using different transfer functions in data-driven models for forecasting wind speed. Usually, the application of the GMDH model only implements the second-order polynomial as a partial description. However, in this study, we implement the hyperbolic tangent transfer function in the GMDH model. The forecasting model’s accuracy is evaluated using mean absolute percentage error (MAPE), root mean square error (RMSE) and mean absolute error (MAE). The results show that the GMDH model with hyperbolic tangent is highly accurate with more negligible computational power than other models. The GMDH-hyperbolic tangent model managed to improve the forecasting performance of the conventional GMDH model by 11.21% in mean absolute percentage error and outperforms other ANN models.
Occupational therapy scope of practice in the rehabilitation of adults experiencing persistent post-concussion symptoms following traumatic brain injury: a scoping review protocol
Authors: Licciardi Lisa , Olver John , Lalor Aislinn , Callaway Libby 
Published: November 2023

Objective:
The objective of the review is to identify, categorize, and examine literature describing occupational therapy scope of practice in the rehabilitation of adults experiencing persistent post-concussion symptoms (PPCS).

Introduction:
PPCS are symptoms experienced by adults a minimum of 2 to 4 weeks after a traumatic brain injury (TBI), and include vestibular, neuropsychiatric, visual, and cognitive issues. Enduring PPCS may result in disability, affecting a person’s independence and/or participation in daily activities. Despite growing recognition of the role occupational therapy can offer in TBI rehabilitation, evidence is limited regarding the scope of practice occupational therapists have in the rehabilitation of adults experiencing PPCS.

Inclusion criteria:
Literature that includes adults (aged 18 to 65 years) experiencing PPCS that describes the occupational therapy scope of practice in concussion programs will be considered for inclusion in this review. Sources reporting on participants aged under 18 years, classified with non-persistent symptoms, and receiving care in acute health care settings will be excluded. Non-English publications or gray literature from civil society or disabled persons organizations or other representative bodies in the field of brain injury will also be excluded.

Methods:
The scoping review will follow the JBI methodology for scoping reviews. Five electronic databases will be searched for literature published between 2013 and the present: MEDLINE, Embase, Emcare, PsycINFO, and CINAHL. Two reviewers will independently conduct title and abstract screening of the results and, upon consensus, independently screen full texts to confirm final sources for inclusion. Any disagreements will be resolved by discussion with a third reviewer. Data will be extracted from included sources and we will then map occupational therapy scope of practice (inclusive of assessments and interventions) against the World Health Organization’s International Classification of Functioning One-Level Classification. Results will be presented in tabular or narrative format.

Thermo-Shock Experiments on Thick-Walled Cylindrical Mock-Ups
Authors: Mora Mendez Diego Fernando , Niffenegger Markus , Mao Gaojun , Baumgartner Beat , Kottmann Hans 
Published: November 2023

Abstract
Nuclear power plants in Europe are entering in a phase of long-term operation (LTO) and one of the key safety assessments for continuing in operation is the evaluation of pressurized thermo-shock (PTS). Since conducting PTS experiments on real-scale reactor pressure vessels (RPVs) are unaffordable and challenging, the present contribution concerns the test facility for performing thermal shock-like cooling on small thick-walled cylindrical mock-ups. The mock-up contains four equally separated notches. Thermal shock (TS) loading condition without pressure is applied. It is expected Mode I of fracture (opening mode) due to pure tensile hoop stresses generated by the cooling. The loading condition represents a fast cooling (from 300°C to room temperature) similar to the transient due to a Loss of Coolant accident (LOCA) in the real RPV. RPV steel 17MoV 8-4 with an artificially (thermally treated material) increased ductile to brittle transition temperature (DBTT) to values similar to a highly-irradiated RPV at its end-of-life is used. The preliminary experimental results show good performance of the thermo-shock facility confirming that the loading conditions are adequate and demonstrating that the thermal stresses developed in the mock-up are high enough to trigger crack growth and arrest of the precracks in the embrittled steel. The results of the current experiment will be used to validate the ongoing numerical PTS assessment with XFEM.
Storage Life and Surveillance of the 9975 Shipping Package
Authors: Hensel Steve J. , O’Grady Andrew J. 
Published: November 2023

Abstract
Plutonium oxide bearing materials stabilized and packaged per DOE-STD-3013 are currently stored at the US Department of Energy Savannah River Site (SRS) in the 9975 shipping package. Additionally, the 9975 package is used to store plutonium bearing materials in non-3013 containers (e.g. nested screw lid, slip lid and food pack can types of containers). The 9975 package was initially given a 10 year storage life. Field surveillance and laboratory studies of the 9975 non-metallic fiberboard and O-ring materials were used to justify a 15-year storage life as minor detectable degradation occurred. Subsequently, a 20-year and most recently a 40-year storage life was established by using degradation data as input to hypothetical design based accident event evaluations. For storage of non-3013 containers within the 9975 package the storage life is limited to 20 years.
Numerical Investigation for an Optimized Procedure of Overlay Welding Repair for the Metal Loss of Large-Scale Structures
Authors: Takahashi Junya , Yamauchi Yuki , Shibahara Masakazu 
Published: November 2023

Abstract
In this study, numerical analyses on the effects of the inter-pass time/temperature and welding pass order were conducted to optimize the welding procedure for reducing the deformation of the pressure equipment owing to multi-pass overlay welding repair. To predict the deformation, a large-scale thermal elastic-plastic analysis based on the Idealized explicit finite element method (IEFEM) was performed, wherein the multi-pass overlay welding repair for the external metal loss of a cylindrical body made of low-carbon steel was simulated. This method accomplished the large-scale computation of the analysis models with 235,236 elements and 18 or more welding passes within a practical duration. The analyses of various patterns of the welding order indicated an evident difference in deformation due to the overlay welding order. In addition, based on the deformation study with varying inter-pass temperatures, it was clarified that as the inter-pass temperature decreased, the deformation in the repaired part could be reduced. Further, the reduction effect peaked when the inter-pass temperature was less than a specific value. These results suggest that the deformation resulting from overlay welding repair could be reduced by controlling the inter-pass time and welding order. The concept for setting the optimal repair procedure is clarified.
A Round Robin Evaluation of Elastic-Plastic Strain Measures for Fatigue Analysis
Authors: Matusin Cory S. , Damiani Thomas M. 
Published: November 2023

Abstract
The rules for performing fatigue assessments of light water reactor pressure vessels and piping are found within Section III-NB and Appendix XIII of the ASME Boiler and Pressure Vessel Code (BPVC). These methods are primarily elastic, utilizing the Tresca-based stress intensity approach to resolve stress amplitudes and, using the design fatigue curve, calculate cumulative usage factors. Elastic-Plastic (EP) analysis rules are prescribed in Appendix XIII and can be used as an alternative fatigue methodology. Currently, Appendix XIII-3440(b) of Section III uses a numerically maximum principal total strain range criteria for EP fatigue analysis, but there are other methods available within other parts of the Code and elsewhere in literature to resolve the EP stress and strain histories for fatigue evaluation. A round robin analysis was organized by the authors to compare some of these alternative EP strain measures against each other and against available test data. Participants evaluated various strain measures for two test articles from a common set of geometry, mesh, and material property information, including prescription of the fatigue curves and environmental enhancement methods to be used in the calculations. The test articles were a thermally shocked stepped pipe and a thick perforated instrumentation ring, both of which have previously been published within the Pressure Vessels and Piping (PVP) Conference proceedings. This paper details the calculations performed by the participants and provides a comparison and contrast of the methods. These results were used to inform proposed changes to the fatigue analysis rules in ASME Section III Appendix XIII that are documented in a companion paper.
Effect of Compression Precracking on the Near Threshold Fatigue Crack Propagation in an AISI 316L Stainless Steel
Authors: Gualdron Plata Javier , Bonazzi Luis , Ruggieri Claudio 
Published: November 2023

Abstract
This work describes an alternative test procedure based on fatigue precracking under compression to mitigate the potential effects of crack closure on near-threshold fatigue data and, thus, to obtain more consistent and reliable ΔKth-values. The method relies on performing a compression precracking, in which both maximum and minimum loads are compressive, thereby resulting in a tensile residual stress field at the crack tip. Fatigue crack growth (FCG) tests conducted on an AISI 316L stainless steel provide the experimental data upon which the near-threshold fatigue crack growth rate data for different test techniques can be determined. Overall, the present investigation shows that combining the compression precracking technique with the utilization of non-standard bend specimens having increased span improves evaluation of the near-threshold fatigue crack growth rate data for the tested AISI 316L steel, thereby providing more accurate ΔKth-values.
Response Combination Method Between Dynamic, High Frequency and Pseudo-Static Responses With Floor Response Spectrum Method Assisted by Time History Analysis for Multiply Supported Piping System
Authors: Yoshida Ayaka , Takayama Yoshihiro , Tsushima Toshiyuki , Hioki Hiroaki , Shudo Hiromichi 
Published: November 2023

Abstract
The independent support motion (ISM) response spectrum method is currently used for multiply supported nuclear piping system. This method requires calculating and combining maximum values of following three responses excited by independent inputs of support excitations: the dynamic response of each mode below the cutoff frequency, the rigid response of the high frequency mode above the cutoff frequency (high frequency response), and the pseudo-static response due to relative displacement at the support point. Here, although the maximum values of each response rarely occur simultaneously, it is difficult to combine each maximum response appropriately because phase information is lost in the response spectrum analysis method. NUREG-1061 issued by the U.S. NRC proposes, based on the analysis results of many multiply supported piping systems, a method that mainly uses the absolute sum rule when combining the maximum values of the dynamic responses by multiple excitations and the SRSS rule when combining the maximum value of the pseudo-static response with the dynamic response. Even with this method, however, it is difficult to avoid excessive overestimation.
The authors have already developed an analysis method for multiply supported piping systems, named SATH method (Spectrum method Assisted by Time History analysis), which combines the maximum value of each dynamic response by each excitation considering the correlation between each response, and have presented it in ASME PVP2020, etc. Then, the SATH method has been improved to add the function that considers the correlation coefficients to the combination of the maximum values of the dynamic response, the high frequency response and the pseudo-static response using the time history acceleration and the time history displacement of each support excitation.
In this paper, the combination method between the dynamic response, the high frequency response and the pseudo-static response in the SATH method is explained, and the advantages of the SATH method is confirmed by comparing the analysis results by the SATH method, by the currently used analysis method (NUREG-1061 method) and by the time history analysis method. The SATH method is found to yield results close to those of the time history analysis method and to avoid excessive overestimation.

Published: November 2023

Abstract
Present study extends the investigation previously carried out on a P91 tee to two of the three component’s welds. Previous studies included both creep analysis and infield tests; component considered is the outflow tubing / manifold tee of the superheater harp, steam generator high-temperature-section. Creep simulation requires extraction of constituent law’s coefficients for the P91 weld metal. Analytical methods base on creep strain and strain rate data. As an alternative to their experimental derivation from an ex-service welded-material sample, present study benefits from literature data availability. Specifically, they come from rupture creep-tests on cross-weld P91 specimens at 600°C and 650°C; the weld sample consisted of as-fabricated P91 two plates, welded by a V-butt joint. Stresses selected are above, close to the operation maximum considered in the analysis. Coherently, instead of the outflow-tube / manifold tee-weld, study now considers the butt joint weld on manifold and the outflow tube. It adopted this choice also for economy of the simulation, weld creep damage calculated through both Larson-Miller theory and Monkman-Grant relation. Comparison of LMP (stress) data from literature sources (base-metal minimum-LMP and weld-metal) shows good consistency. For the manifold’s weld, API 579-1 and FEM stress analysis have predicted expended life percentage of 24%. For the outflow tube’s weld, master curve method and manual stress analysis have predicted similar expended life percentage.
Analysis of the Effect of Pre-Crack Curvature in Mini-C(T) Specimen on Fracture Toughness Evaluation

Published: November 2023

Abstract
The appropriate test method for determination of reference temperature (To) using the Master Curve is necessary for the structural integrity assessment of the reactor pressure vessel, prescribed in ASME CC N-830-1 and JEAC4206-2016. To can be determined using the fracture toughness test specimen, such as miniature C(T) (Mini-C(T)), following ASTM E1921 or JEAC4216, which prescribe the test method including pre-crack straightness criteria. Part of the requirements in the ASTM E1921 were revised after a decade. Additionally, the ASTM’s allowable crack front curvature of the specimen has become different from that of the JEAC. Given that the pre-crack curvature of the Mini-C(T) specimen might affect the To determination because of the variation of the plastic constraint. Herein, we evaluated the effect of the crack curvature on the fracture toughness (KJc) evaluation or To determination using the Mini-C(T). The finite element analyses (FEAs), including the Weibull stress analysis, were employed to provide quantitative information on the requirement of the pre-crack curvature in ASTM E1921 and JEAC4216. FEAs revealed that the specimen with an upper limit on the curvature decreased the plastic constraint, indicating a higher KJc value. The Weibull stress analysis showed that the straightness requirement according to JEAC4216-2015 was reasonable for the To determination. However, when the specimens with upper limit crack curvature per ASTM E1921-21 were used for To determination, the To was lowered significantly.
Influence of Aspect Ratio of Sheets on Flutter Characteristics
Authors: Hiroaki Keiichi , Watanabe Masahiro 
Published: November 2023

Abstract
Thin flexible sheets are used in numerous engineering applications, e. g. polarizing films and papers. In their manufacturing processes, the sheets subjected to high-speed fluid flow. Then, the flutter is caused to the sheet due to the interaction of fluid flow and sheet motion. The violent fluttering motion can cause serious damage to the sheet such as winkles and scattering of coated liquid on the sheet. Thus, a deeper understanding of flutter characteristics is crucial to avoid the flutter. In this study, the influence of an aspect ratio (ratio of chord and span length) of sheet, that is, three-dimensional effect on flutter characteristics (flutter velocity and amplitude) is investigated by a nonlinear analysis. A nonlinear fluid-structure interaction model is developed. The sheet is modeled as a cantilevered two-dimensional beam. The nonlinearity due to large deformation is considered in the modeling. Moreover, the fluid force acting on the sheet surface is calculated by the three-dimensional vortex-lattice method based on potential flow to consider span-wise distribution of the fluid force. Flutter amplitudes (amplitudes under limit cycle oscillation) are calculated varying the flow velocity. Following results are obtained in the present study: (1) The flutter amplitudes become large as the aspect ratio of the sheet increases. (2) The flutter velocity tends to decrease as the aspect ratio of the sheet increases.
Towards an Improvement of Allowable Planar Flaws of ASME Code Section XI Acceptance Standards for Ferritic Steel Materials
Authors: Lacroix Valéry , Dulieu Pierre , Hasegawa Kunio 
Published: November 2023

Abstract
In case of flaw detection during In-Service inspection of nuclear components, ASME Code Section XI provides Acceptance Standards to determine whether the flaw can be considered as harmless or should be further evaluated.
For ferritic steel materials, the size of allowable planar flaws is given in Table IWB-3510-1. To facilitate the assessment, the allowable flaw size only depends on three parameters : the component thickness, the flaw aspect ratio and the proximity of the flaw to the surface. However, a graphical analysis of the impact of those parameters highlights some inconsistencies. The allowable flaw depth evolution is discontinuous between the ranges of thickness. Besides, the allowable flaw depth increases indefinitely with component thickness, which is not consistent with finite fracture toughness of materials. Finally, while the aspect ratio dependence of the allowable flaw depth has been clearly described in EPRI NP-1406-SR (1980), no clear technical basis has been found to explain the component thickness dependence. Consequently, the need to revise the allowable planar flaws of ASME Code Section XI Acceptance Standards using a robust technical basis is brought to light.
This paper details the inconsistencies related to the present allowable planar flaws table and proposes improvement points to revise the allowable planar flaw Table IWB-3510-1.
Revision of Allowable Planar Flaw Tables of ASME B&PV Code Section XI for Ferritic Steel Materials
Authors: Dulieu Pierre , Lacroix Valéry , Hasegawa Kunio 
Published: November 2023

Abstract
When in-Service inspection detects flaw in nuclear components, Acceptance Standards of ASME Code Section XI provide allowable flaw sizes to assess the flaw severity and to identify the need for further evaluation. For ferritic vessel welds, the size of allowable planar flaws is given in Table IWB-3510-1.
Considering some inconsistencies highlighted in this table, a revision using a robust technical basis is conducted. For that purpose, a methodology is developed following ASME philosophy and including some basic criteria to ensure component safety by preventing plastic collapse and brittle failure. As far as the prevention from plastic collapse is concerned, a uniform limit load reduction is considered whatever the flaw aspect ratios. For the prevention of brittle failure, a reference surface flaw configuration (flaw size, aspect ratio and component thickness) is defined to derive a reference stress intensity factor that should not be exceeded. Then, all the flaw configurations corresponding to this reference stress intensity factor are identified to derive a set of allowable flaw size curves. At last, the most penalizing flaw sizes between both failure modes are retained to define the new allowable flaws.
This methodology is applied to surface flaws with various aspect ratios and component thicknesses. It is also coherently applied to subsurface flaws considering the proximity of the flaw to the surface as an additional parameter. Finally, a revision of the allowable planar flaw Table IWB-3510-1 of ASME Code Section XI Acceptance Standards is proposed.
