TITLE: Corrosion Problems of Power Reactorl Cooled by Car-bon Dioxide
PERIODICAL: Jaderna" energie, 1960, No. 6, pp. 192 199
TEXT: The article deals with the extent and significance of corrosion pro b-
lems encountered in nuclear power reactor engineering, with special attention to
C02-cooled reactors which represent 52.4% of the total output of nuclear power
plants already in operation or scheduled to be put in operation by 1962, In these,
reactors, the primary-loop COo coolant works within a temperature range of 100 -
- 500, OC and at pressures ranging from 7 to 65 atmospheres, depending on the speci-
fic design of the individual reactors. During the coolan-1-circulation, about one
half of the total coolant gas is found in the region of intensive radiation at all
times. As a result, an interaction between the gas and the wall materials as well
as changes in the coolant composition take place. Principal reactions cc-curing
under operating conditions are listed in Table 1 and are referred to by their num-
ber in (). By radiolytic processes, i.e., lonlza~,ion tReaction 1) and excitation
(Reaction 2), CO2 is decomposed into CO and 0 (in atomic state), Die to tbe in-

fluence of radiation, a partial recombination of both components takes place (Re-
action 4). The net yield of the radiolyti_9 deco Imp6sition depends on the gas tem-
perature and on the presence of graphite.19 In the absence of graphite,.radtoly-Uc.
formation of CO was not observed 4VET-Wt-temperatures as high as 3000C. The. corro-
sion effect of the coolant is that of oxidation promoted by the oxygen contamina-
tion of the coolant. The actual content of 0 in the loop under operating condi.-

t~ions cannot be determined due to the uncertainty as to how great-is the oxygen
increment originating from the newly Introduced replacements of gas and from the
radiolytic and thermal decomposition Of C02, and how great is the 02 decrement
due to the oxidation of tht loop-walls by the reactions (7) through (14). An
approximate idea to this effect can be obtained from a gross oxygen balance as
shown-in Table 2 which, however, does not consider changes due to the COP decom-
position. The high values of free enthalphy-,6 G in the reactions (7) through (14)
indicate that the predominant oxidation is due-to free oxygen. Besides oxygen,
oxidation processes are also effected bv Co,~, as ca-n,be seen from,the reactions
(15) through (19) and by CO, as can be seen-from the reactions (2-2) I.-h-rough- (25)-
1n the latter two cases the enthalpies are considerably lower.. but still favorable
for oxidation processes. During oxidation of magnesium-type cladding materials,

C02 is reduced to CO, Reactions (20) and (21) point to the formation of carbon-
ates. In fact, MgCO 3 is found In the oxidation layer up to a temperature of 45oOc,
while there is no formation of FeCO3. The probability of GO having an oxidizing
effect is always greaterthan that of its having a reducing effect as shown.by
reactions (26), (27), (28), and (30) with the,exception of the formation of m'ag-
netite from hematite by the reaction (29). The formattion oil' iron pefitacarbonyl
Fe(CO) occurs in exceptional cases only as itis completely decomposed at 1.00'r;
(Ref. 9), provided that thereaction reaches a state of equilibrium~ The CO con-
tent of the coolant is higher in graphite reactors due to the C02 oxidation of gra-
phite by the reaction (6). It can be seen from the reactions (1),through (36) - '/ "
that these processes cannot be conside-red separately, but only -;n -their entirety,
rendering their quantitative evaluationvery difficult. Nevert-heless, the "Lollo-
wing conclusions on the reactions.taking place in thF primary loop can.be made~
a) Oxidation is caused not only byoxygen,~ but also by C02 pnd traces of C04
b) The CO content in graphiteless reactors -Js usually less than 1%'and its infill-
ence can be neglected,, c) The state of equilibrium between H?O and concentra.-
tions prevents an accumulation of H2 but.. all the same time, is responsible for 4-he

have to be considered. d) The effects of. radiation.on reactions iefluencing th6.
coolant composition have not yet been explored sufficiently, but 11 is assumed
they are of no substantial significance, The most Important corrosion problem.t~l
in
all reactors is that of oxidation of the pr6ssure-vessel steel walls and the fuel
element cladding, As for the oxidation of steel, it was found that the composiiim
and nature of scales forming at temperatures belo 5700C is qt4ite different from.
w
those forming at kilgher temperatures. Their principal component is magnetite whose
formation is independent c4f the coolanz; gas (Pefs. 13 and 15.1. The part-1 r_--luation.
of C02 and CO in the oxidation of iron is evident. from th~ preeence of carbon,
which is found dispersed In the oxydaUon layer., Howevar, no signs of oarbor-kiza-
tion of the steel were observed. Physloal. propert."-:~s of oxidation products -are of

all these plants use magnesium alloys and beryllJum. Of these, best. results were
obtained with the British Magnoxtype alloys., the French Mg-Zr alloy and the Soviet
Mg-Be clad obtained by simultaneous vacuum dd .1"fusion of both -:;ont ponents, , The com-
position of these materials is shown in Table 1. The Soviet Mg-Be diffusion clad
hEs the advan-'Vage of containing more Be than can be achieved by alloying. ThIs
cladding material was designed for operation at 5000C, but. it remains corrosion-
-resistant even at 625'c and can withstand temporary temperatures as high as 750
- 8OOoC. It can "heal" damaged spots on its surfao-e due tc the free Be diffused
in the subsurface layers. These.excellent properties.of the oxide layer are due
to the enrichment by BeO achieved by preferential diffusion of Be and the evapora-
tion of Mg especially at higher circulation speeds of the gas. The disa&wltage
of the diffused clads Is their difficult fabrication technologY4 (Editors: 0,

TEXT. Based on the statistical processing of mechanical test-results of
5283 samples of 1232 different heats of 4 steel grades (25, 35, 45 arui 55), the
aependence of 6b'afid 85 on the chemical composition 6f pte~el was established.
The limit content of basic elements in the tektd-steels was as-follows (in
