  1. 1. SSRT of 10-4 FeCrAl in LBE and Pb to Characterize Liquid Metal Embrittlement Effects

    Master-uppsats, KTH/Fysik

    Författare :Daniel Stein; [2022]
    Nyckelord :Liquid Metal Embrittlement; Lead; Bismuth; Lead-Bismuth Eutectic; Slow Strain Rate Testing;

    Sammanfattning : In this work the susceptibility of Fe-10Cr-4Al steel to liquid metal embitterment (LME)in low oxygen environment was investigated. slow strain rate testing (SSRT) wereconducted on 10-4 FeCrAl steel in a stagnant lead from 340-480◦C, lead-bismutheutectic (LBE) from 140-450◦C and lead-bismuth mixture at 375◦C with increasingbismuth content from 0.

  3. 2. Optimisation of the bottom stirring praxis in a LD-LBE converter : Investigations and tests on phosphorous removal, nitrogen as stirring gas, and slopping

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :José Aguirre Castillo; [2015]
    Nyckelord :LD; BOS; Bottom Stirring; Phosphorous; Steel making; Nitrogen;

    Sammanfattning : The LD-process, called after the cities Linz and Donawitz, is used to convert pig iron into crude steel by blowing oxygen on top of the pig iron. A LD-LBE converter, Lance Bubbling Equilibrium, also stirs the melt trough a bottom stirring system. LÄS MER

  4. 3. CONQUER CORROSION : Key issues of the lead-cooled fast reactor design

    Uppsats för yrkesexamina på avancerad nivå, Tillämpad kärnfysik

    Författare :Mathias Hareland; [2011]
    Nyckelord :Nuclear power; Generation-IV; lead cooled fast reactor; LFR; corrosion; MAXTHAL; MYRRHA; Lead-bismuth eutectic; LBE;

    Sammanfattning : The lead-cooled fast reactor (LFR) is one of the concepts of the Generation IV reactorsystems. There are some issues that have to be solved before a research orcommercial LFR can be built. LÄS MER

  5. 4. Tolkning av begreppet betryggande i lagstiftning om brandfarliga och explosiva varor med fokus på betryggande avstånd.

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Alexander Claesson; [2011]
    Nyckelord :Sprängämnesinspektionen; SÄIFS; adequate; reassuring; MSB; gas vessel; Reason; Swiss Cheese Model; impact calculations; risk acceptance criterion; injury criteria; risk evaluation; betryggande; gascistern; Schweizerostmodell; lagen om brandfarliga och explosiva varor; LBE; konsekvensberäkningar; acceptanskriterier; skadekriterier; Technology and Engineering;

    Sammanfattning : The concept of adequate/reassuring (betryggande) safety in Swedish legislation for flammable liquid and gas is very hard to verify in established risk analysis methods. The difficulty lies in the fact that the concept of ade-quate/reassuring safety is only formulated in qualitative terms. LÄS MER

  7. 5. Application of CFD to Safety and Thermal-Hydraulic Analysis of Lead-Cooled Systems

    Master-uppsats, KTH/Fysik

    Författare :Marti Jeltsov; [2011]
    Nyckelord :Coupled Codes; Verification Validation; CFD; System Thermal-Hydraulics; Lead Cooled sys-;

    Sammanfattning : Computational Fluid Dynamics (CFD) is increasingly being used in nuclear reactor safety analysis as a tool that enables safety related physical phenomena occurring in the reactor coolant system to be described in more detail and accuracy. Validation is a necessary step in improving predictive capability of a computationa code or coupled computational codes. LÄS MER
