A perfusion reactor is a bioreactor designed to continuously supply nutrients and remove waste products from a culture of cells or microorganisms. This system allows for a constant flow of fresh medium, promoting optimal growth conditions and enhancing product yield. Perfusion reactors are commonly used in biotechnology and pharmaceutical applications for the production of proteins, antibodies, and other bioproducts. They can be operated in various configurations, including hollow fiber, stirred tank, and fixed bed systems.
Reactor period is the time is takes for a reactor's power to increase by a factor of e (2.71828).
a reactor is generally termed as an autoclave reactor,when it is a high pressure batch reactor.mostly this kind of reactors are used for sterilization the reactants..
Probable you think to a breeder reactor; this type of nuclear reactor produce more fissile material than it consumes.
Kalpakkam has both Thermal reactor (Madras Atomic Power Station) and Fast Breeder Reactor -FBTR and PFBR (Under construction). In MAPS (thermal reactor) it is Heavy Water (D2O) Which acts as a coolant as well as moderator, where as in Fast Breeder Test Reactor (FBTR) and Prototype Fast Breeder Reactor (PFBR) Sodium (Na) is used as coolant. Since there should not any moderators for fast reactors D2O will not be used as coolant in fast reactors.

Perfusion model is normally chosen for the production of unstable proteins. This is because perfusion culture has low resident time in bioreactor and the product can be harvested and purified promptly. In addition, it can avoid the accumulation of toxic or inhibitory metabolites that might have negative impact on the productivity of fed-batch cultures. Perfusion cultivation is carried out by continuously feeding fresh medium to the bioreactor and constantly removing the cell-free spent medium while retaining the cells in the reactor; thus, a much higher cell density can be obtained in perfusion cultures compared to continuous cultures, as cells are retained within the reactor via a cell retention device. The perfusion rate depends on the demand of the cell line, the concentration of nutrients in the feed, and the level of toxification.

referred to as perfusion. Adequate perfusion ensures that cells receive enough oxygen and nutrients to function properly and remove waste products. Maintaining proper perfusion is essential for overall organ and tissue health.

Tissue perfusion is the amount of blood that the tissues receive during circulation. When a person has decreased tissue perfusion, the tissues are receiving inadequate blood supply.
The perfusion phase is the part of a contrast scan in which the contrast is moving into the blood vessels.
In reference to physiology perfusion is the process of blood being delivered to a capillary bed in the biological tissue. Normal levels of perfusion can be tested by looking at skin color or skin temperature.

Vascular perfusion refers to the process by which blood is delivered to tissues and organs in the body. It is essential for providing oxygen and nutrients to cells and removing waste products. Proper vascular perfusion is crucial for normal tissue function and overall health.
