    • Finite Element Analysis CapabilityCase Study: Flask Impact Design SubstantiationTo support and substantiate the design of a nuclear storage flask and internal assembly, dynamic impactanalysis was performed by Assystem UK to show that the ability of the container to safely hold its contentswould not be comprised through any impact that could occur through being dropped during transit.The flask has been designed to provide a safemethod of containment for nuclear material. Theflasks are to be kept in a storage facility wheredrop scenarios are possible. Two drop heightswere analysed, each with nine different droporientations (see example, bottom right).The FEA mesh of the flask components wasgenerated using Altair Hypermesh and analysedusing RADIOSS v.4.4u, both of which are part ofthe Altair Hyperworks suite.The study identified five different possible failuremodes, each of which was investigated for bothdrop heights and all drop orientations. The modeof most concern was the failure of the dynamicsealing of the flask. This involves the sealsbeing momentarily misaligned during impact andallowing the escape of a limited, but dangerous,amount of gas.The substantiation showed that, with the design and drop heights specified, the ability of the flask to holdits contents would not be compromised. This design was physically tested at the Assystem UK workshopfacility, and all tests were in agreement with the above analysis.

    • Fracture Analysis CapabilityPresentation of Margins of SafetyFracture margins based on material fracture toughness with respect to operational temperatures (includingtransition regions). These calculations account for crack tip plasticity and allow safe operatingtemperatures to be identified Cracked body analysis can be carried out for assessments against the Failure Assessment Diagrams (FAD). Finite element analysis is used to determine the Kr (J-integral) and Limit Load Analysis to determine Lr. Pressure vessel design and assessment to all major codes (ASME III / VIII, PD5500, EN13445 etc.) Primary circuit and secondary side components (eg steam generators, regenerative heat exchangers).Design and hydrotest conditions and Level A (fatigue) operation. Recent assessments moving towardsstrain predictions and away from stress linearisation (or planarisation). Fatigue life evaluation (or re- evaluation based on measured transient blackbox information) carried out in accordance with design codes (eg ASME III) or using modern stress-life and strain-life techniques. A key aspect in plant operation is life extension (aging plant or extension of existing Safety Justifications) therefore knowledge of pessimisms in fatigue calculation is vitally important. Public domain RPVFatigue evaluation can be carried out elastically in accordance with design rule codes, or optionally,elasto-plastically to check for shakedown as well as provide strain ranges for strain-based fatiguecalculation.Non-linear material models(e.g. nonlinear kinematicplasticity) used in assessmentwith life-cycle loading applied.

    • Seismic Analysis CapabilityCase Study: Waste Vitrification Process (WVP)Including details of Residue Export Facility (REF), In-Cell Cranes and Seismic De-sign SubstantiationIn support of the Design Substantiation Report (DSR) produced bySellafield Ltd., Assystem provided the as-built seismic designsubstantiation of the In-Cell Cranes and their rail systems for WVPREF. At the time, the equipment was already installed andundergoing final commissioning but a robust seismic substantiationfrom the design stage was lacking.The substantiation was based on a response spectrum analysis ofbeam element F.E. models of structures. These gave forces andmoments within structures from which code assessment of structuralmembers were made using spreadsheets whilst local design detailswere assessed by hand calculations using Mathcad. Overhead Jib craneThe main body of the report reflected the DSR content whilst the supporting detail was placed inappendices; this enabled Sellafield Ltd. to quickly transfer the required information into the DSR.Substantiation required demonstration of the ability to meet a number of System Functional Requirementsagainst the Design Basis Earthquake (DBE) loading with a further demonstration of margins against cliffedge effects, the Margins Earthquake (1.4 times DBE). This was achieved by demonstrating that thedesign maintained an elastic and ductile response under the DBE, using a code based assessment, with aperformance based assessment to provide confidence against cliff edge effects.The assessment was based on a demonstration of an understanding of the ultimate failure modes of thestructure, taking into account: Redundancy or alternate load paths Ultimate capacity of components Reduced loading due to increased dampingA significant part of this demonstration was achieved based on the reserves demonstrated against theDBE loading; where this could not provide the required confidence then an assessment was made usingone of the following: Reasoned argument (simple or in depth) with no further analysis Additional simple analysis Additional in depth analysisAlthough the assessment raised a number of technical challenges it was completed successfully; thereport was accepted with only a small number of minor comments.

    • Marine Hydrodynamics CapabilityCase Study: Vessel Motion AnalysisOffshore equipment must be designed to withstand, or exploit, the forces and motions that areexperienced as a result of the waves and associated vessel motions. Vessel motion analysis acts toprovide a more complete understanding of what these forces and motions will be under normalcircumstances, and what extreme occurrences could be expected, and how often.This understanding supports Lloyd’s and DNV codes and can feed straight into design reviews givingengineers the confidence to choose more optimised designs or highlight potential issues to them. Thuscost is saved through the reduction of over-engineering and time is saved through the reduction of designiterations. It is most effective to use this approach as close to the concept design phase as possible.The sample graphs below show common output types from vessel motion analysis. The upper graphshows the probability distribution for exceeding a maximum surge acceleration within a specified timewindow for a given position on a vessel. The lower graph shows what proportion of time is spent inexcess of a given resultant acceleration for a given position on a vessel.In the examples shown the analysis was performed for given significant wave height values. All sea-statesof that height which occur at the location of interest were analysed, and the individual probabilitiescombined and weighted appropriately to give a complete analysis for the wave heights of interest at thelocation of interest.The analysis shown below is specificto one example, but similar analysiscan be tailored to customer needs. Itis common to perform similaranalysis for resultant and componentvelocities and positions, as well asaccelerations. In addition, analysiscan be performed for water motionsor wave forces acting on subseaequipment.
