Following the arrival of a key safety vessel, the Fennica, to the Chukchi sea, Shell was allowed to commence its drilling program.
A 10 m increase in chimney height resulted in a 5 °C decrease in the main and safety vessel temperatures.
A safety vessel is incorporated in the sodium cooled fast reactors surrounding the main vessel to contain the sodium, in case of a leak in the main vessel.
This paper presents the determination of dynamic pressures on the main vessel as well as safety vessel generated due to fluid structure interaction effects under seismic excitations.
A 10% increase in the whole size of CLEAR-I RVACS resulted in a 20 °C decrease in the main and safety vessel temperatures.
This paper traces the experiments and simulations in the key developments of a robotic device, for the ISI of main vessel and safety vessel of FBRs, carried out at Indira Gandhi Centre for Atomic Research, India.
Some of the design changes include, (i) provision of four primary pipes per primary sodium pump, (ii) inner vessel with single torus lower part, (iii) dome shape roof slab supported on reactor vault, (iv) machined thick plate rotating plugs, (v) reduced main vessel diameter with narrow-gap cooling baffles and (vi) safety vessel integrated with reactor vault.
These apart, the application of these numerical analyses for the 500 MWe Prototype Fast Breeder Reactor PFBRR) demonstrates the structural integrity of safety vessel under the seismic loadings during main vessel leaked condition and quantifies the design basis loads for the inner wall of the reactor vault.
When the platform blew 167 out of 228 workers either on the rig or one of the safety standby vessels patrolling it died.
The DCM replied that the U.S. places the highest priority on the safety of vessels and human life at sea, and added that if any violations of U.S. law are discovered, we will take appropriate enforcement action.
