If available, inhabitants may take potassium iodide at the rate of 130 mg / day per adult ( 65 mg / day per child ) as an additional measure to protect the thyroid gland from the uptake of dangerous radioactive iodine, a component of most fallout and reactor waste.

If the nuclear reactor is left on the ground and its energy transmitted to the spacecraft, the weight of the reactor is removed as well.

If the reactor and the ballistic missiles explode while the K-19 is surfaced, the resulting nuclear blast will destroy not only the K-19 but also the nearby US navy ship and, most likely, the NATO base as well.

If cooling fails during this post-shutdown period, the reactor can still overheat and meltdown.

If heavy water is used, it is possible to operate the reactor with natural uranium, but the production of heavy water requires large amounts of energy and is hence expensive.

If helium is used, because it is lighter than air, air can displace the helium if the reactor wall is breached.

If the heat from that reaction is not removed adequately, the fuel assemblies in a reactor core can melt.

If the reactor coolant pumps are not running, the upper part of the core will be exposed to a steam environment and heatup of the core will begin.

If necessary, the emergency power supply allows the safe shut down of the nuclear reactor.

While criticality at fast energies may be achieved with uranium enriched to 5. 5 weight percent Uranium-235, fast reactor designs have often been proposed with enrichments in the range of 20 percent for a variety of reasons, including core lifetime: If a fast reactor were loaded with the minimal critical mass, then the reactor would become subcritical after the first fission had occurred.

If all of the independent cooling trains of the ECCS fail to operate as designed, this heat can increase the fuel temperature to the point of damaging the reactor.

If the coolant is a liquid, it may boil if the temperature inside the reactor rises.

If the void coefficient is large enough and control systems do not respond quickly enough, this can form a positive feedback loop which can quickly boil all the coolant in the reactor.

If the reactor overheats, thermal expansion of the metallic fuel and cladding causes more neutrons to escape the core, and the nuclear chain reaction can no longer be sustained.

If the reactor vessel developed excessive heat or lost electric power to the air cooling, the plug would melt ; the FLiBe would be pulled out of the reactor core by gravity and criticality would cease as the salt lost contact with the graphite.

If the reactor is shot enough the turrets will cease firing for a short amount of time.

If the refiner wants to produce alkanes ( i. e., hydrocarbons present in natural gas, gasoline, and diesel fuel ), the coal gas is collected at this state and routed to a Fischer-Tropsch reactor.

If the primary cooling loop were to be somehow suddenly stopped, or if the control rods were suddenly removed, the metal fuel can melt as accidentally demonstrated in EBR-I, however the melting fuel is then extruded up the steel fuel cladding tubes and out of the active core region leading to permanent reactor shutdown and no further fission heat generation or fuel melting.

If no cooling system is working to remove the decay heat from a crippled and newly shut down reactor, the decay heat may cause the core of the reactor to reach unsafe temperatures within a few hours or days, depending upon the type of core.

If he is the child of nothingness, if he is the predestined victim of an age of atomic wars, then he will consult only his own organic needs and go beyond good and evil.

If a broader Atlantic community is to be formed -- and my own judgment is that it lies within the realm of both our needs and our capacity -- a ready nucleus of machinery is at hand in the NATO alliance.

If ever a rifle met the needs of the whitetail hunter, this is it.

If the balance factor becomes 0 then the height of the subtree has decreased by one and the retracing needs to continue.

If the balance factor becomes − 2 or + 2 then the subtree is unbalanced and needs to be rotated to fix it.

" If this is not an error for " ANaesthetic ", then it needs to be added as a noun sense to Wikipedia / Wiktionary?

If a new player feels that he or she needs assistance in learning the rules of craps, it is recommended to approach an empty craps table at a slow time of day ( for example, between 9 a. m. and 11 a. m .).

If the 5 ' nucleotide needs to be removed during proofreading, the triphosphate end is lost.

If a second party from a region wants to join the first party needs to agree, these two parties will then form a common delegation with one vote.

If the cell is synthesizing DNA each pore complex needs to transport about 100 histone molecules per minute.

If the cell is growing rapidly, each complex also needs to transport about 6 newly assembled large and small ribosomal subunits per minute from the nucleus to the cytosol, where they are used to synthesize proteins.

If total cash available is less than cash needs, a deficiency exists.

If one needs a weapon for self-defense one must " prove that his personal safety at risk to such an extent that in order to ensure the needed a weapon for security ".

If the constituency is in a jurisdiction using list PR in its multimember districts ( MMDs ) the winning candidate needs a relative majority of the votes to win, so that the election in the SMD is by first-past-the-post.

If this stage is not performed well, it is unlikely that the project will be successful in meeting the business ’ needs.

If an eavesdropper intercepts the two bits, she may know exactly what Bob needs to do in order to recover the desired state.

If it needs to be loosened, the reamer, or any similar long pin can be used.

“ If, as the writer believes Schiller, various private cases of action were available in satisfying commercial needs, the state was acting in exactly the same fashion as it does at the present day .”

If a feature was intended to be located from the center of the part, the operator needs to locate it from the center of the model, not, perhaps, from a more convenient edge or an arbitrary point, as he could when using " dumb " solids.

If a dealer needs to manually intervene, this will often mean a larger fee.

If a color needs to be added, the glass powder can be " enhanced " with copper or other metal oxides as well as elements such as sodium, calcium, potassium etc.

If the emergency room is overloaded, patients must be treated in an order based on their determined medical needs, not their ability to pay.

* If a process needs to wait for a resource ( wait for user input or file to open ...), it is assigned the " blocked " state.

In universal algebra, a subalgebra of an algebra A is a subset S of A that also has the structure of an algebra of the same type when the algebraic operations are restricted to S. If the axioms of a kind of algebraic structure is described by equational laws, as is typically the case in universal algebra, then the only thing that needs to be checked is that S is closed under the operations.
