  1. 1. Unsteady flow analysis of secondary steam inside a moisture separator

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Alfred Sederlin; [2019]
    Keywords : ;

    Abstract : A variety of method are applied in order to assess the force loads induced by the unsteady flow of steam on a plate structure inside a moisture separator at Forsmark nuclear power plant. The plate structure is suffering from cracks and structure failure which are to be investigated to see if they arise from fatique loads induced by the fluid flow. READ MORE

  3. 2. Crack propagation calculations in non-elastic metals

    University essay from Luleå tekniska universitet/Material- och solidmekanik

    Author : Máren Ingá Baer; [2018]
    Keywords : crack propagation; fracture mechanics;

    Abstract : It is important to know the lifespan of a component, thus services can be planed. At Siemens Industrial Turbomachinery AB (SIT AB) develop and produce gas and steam turbines, the turbines are heavily strained by thermal and centrifugal forces during their life span which lead to cracking.

  4. 3. CFD simulation of pool dynamics in a nuclear reactor's condensation pool

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Anders Jansson; [2014]
    Keywords : CFD; computational fluid dynamics; condensation pool; pool dynamics; nuclear reactor; CFD; beräkningsströmningsdynamik; kondensationsbassäng; pooldynamik; kärnkraftsreaktor;

    Abstract : In a nuclear reactor the containment protects the environment from radioactive emissions. It is separated in two parts, a drywell and a wetwell. The drywell contains the reactor vessel and the steam pipes. If a steam leakage occurs in this part of the containment the pressure will increase. READ MORE

  5. 4. Enhancing the Thermo-Economic Performance of a Direct Steam Generation Solar Tower Power Plant through the Implementation of Steam Flow Control Strategies for Flexible Operation

    University essay from KTH/Kraft- och värmeteknologi

    Author : Farid Ellakany; [2014]
    Keywords : DSG; CSP; steam flowrate control; varrying capacity; flexible operation; solar tower;

    Abstract : Above 90% of the current installed concentrating solar power plants are based on conventional steam-turbine cycles. The operation of steam turbines in these plants is distinctive when compared to traditional base-load power plants. READ MORE

  6. 5. Benchmark of RELAP5 Check Valve Models against Experimental Data

    University essay from Mekanisk värmeteori och strömningslära; Tekniska högskolan

    Author : Jens Gardell; [2013]
    Keywords : RELAP5; check valve slam; steam bubble collapse; experimental data; Benchmark; inertia check valve; pressure wave; closing time; reactor safety;

    Abstract : The use of check valves in the nuclear industry is of great importance from a safety precaution point ofview (McElhaney, 1995). Choosing check valves for these high-pressurized systems comes with agreat challenge. The valves causes what is called check valve slams when closing, leading to a hugepressure wave traveling through the system. READ MORE
