  1. 1. Irradiation Embrittlement on a Core Shroud from Decommissioned BWR

    University essay from KTH/Fysik

    Author : Åsa Bjåland; [2023]
    Keywords : hardness; Vickers hardness test; ATT; yield strength; irradiation embrittlement; welds; hårdhet; Vickers hårdhetstest; ATT; sträckgräns; bestrålningsförsprödning; svetsar;

    Abstract : Irradiation embrittlement is a problematic issue for internal structures, such as acore shroud, in a light water reactor. It is characterized by decreased ductility andtoughness, and increased yield strength and hardening due to increased dislocations. READ MORE

  3. 2. Acoustic properties of a 5G Telecom Equipment Shroud Design for Noise suppression

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : David Andersson; [2021]
    Keywords : Acoustics; 5G; Shroud; Telecom; Noise reduction; Akustik; 5G; Kåpa; Teleutrustning; Ljudisolering;

    Abstract : As technology moves forward it has a tendency to consume more and more power that needs to be cooled by bigger and louder fans, this is especially true for the new generation of 5G radio equipment. This Master thesis is a collaboration with Ericsson and attempts to construct a shroud for containing a number of 5G radio units whilst attenuating the fan noise of the units as effectively as possible.

  4. 3. Thermal Properties of a 5G Telecom Equipment Casing Design for Noise Suppression

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Per Rundström; [2021]
    Keywords : Acoustics; Casing; Shroud; Telecom; Thermal; Akustik; Hölje; Strömningsmekanik; Telecom; Värmeöverföring;

    Abstract : Around the world the implementation of the 5G mobile network is under way. With this latest generation of mobile data transfer comes many advantages compared to the previous generations. One tradeoff however is the reduced range of the transmitting radios due to the higher frequencies of the signal. READ MORE

  5. 4. Investigation of performance and surge behavior of centrifugal compressors through CFD simulations
