FE Simulation of Bolt-up Process for Press-Retraining Bolts of HTR-PM Pressure Vessel
The reactor pressure vessel FE model with 42 M88 bolts is built in this study by ADVEN-TURECluster.These 42 bolts are divided into seven groups,and there are two steps in the bolt-up process.The simulation results show that every bolt-up step will make different influence to different groups of bolts.
Needs of national development in all countries, progressing European co-operation ::: and association as well as globalisation have caused in last few years a particular ::: challenge (also) to higher education systems and institutions. The response to this ::: challenge in Europe is widely known today as the Bologna process. Four years after ::: signing the Bologna Declaration (1999) with its six main “action lines”,1 and two ::: years after Prague communique (2001) which added three further “action lines”2 to ::: the list, the process of establishment of the European Higher Education Area (EHEA) ::: deepened to the institutional level.
