Safety storage calculation

Application to Safety Storage Calculation of a Chemical-processing Plant... 

In the present section, we carry out a sample calculation for the safety storage requirements in a chemical-processing plant. The calculation is based on the infinite niedium pne-veloci model-... 

The manufacturing cost consists of direct, indirect, distribution, and fixed costs. Direct costs are raw materials, operating labor, production supervision, utihties, suppHes, repair, and maintenance. Typical indirect costs include payroll overhead, quaHty control, storage, royalties, and plant overhead, eg, safety, protection, personnel, services, yard, waste, environmental control, and other plant categories. However, environmental control costs are frequendy set up as a separate account and calculated direcdy. The principal distribution costs are packaging and shipping. Fixed costs, which are insensitive to production level, include depreciation, property taxes, rents, insurance, and, in some cases, interest expense. 

Determination of the required capacity of the pressure safety valves (PSVs) involves a calculation that considers the approximated amount of heat that a fire would send into the storage tank and the properties of the tank contents as they are being vaporized by that heat and generate the vapors to be relieved through the valve. The details of this calculation are beyond the scope of this discussion, and the reader is advised to review Chapter 7.15 in the fourth edition of Volume 1 of the Instrument Engineers Handbook if that information is needed. Once the required PSV capacity is determined, the orifice area required to handle that capacity can be obtained graphically. 

Subcriticality of spent core of KM-1 stand stored at special storage facility calculated at NlTl in 1987 and coordinated with Nuclear Safety Department of IPPE was estimated as complying with the nuclear safety requirements, Keff<0.92 . Nuclear and radiation safety of SRU storage is ensured via ...
