X-1 presents a schematic diagram of the VKR-MT power unit. Figure X-1 shows only heat exchangers of the systems of district heating and industrial steam production. Heat exchangers of the intermediate circuit of a district heating system are not shown. The steam turbine plant has no such potentially non-reliable components as high-pressure heaters or low pressure reheaters of steam, which contributes to its high reliability. The reduction of moisture in steam at turbine outlet down to an acceptable level is accomplished by the use of two-stage steam separation and by the separation devices located inside the turbine.

X-8 shows one example from the calculated results for the internal pressure rise vs. bum-up, which is essentially caused by the FP gas released from the fuel pellets.

X-9 shows a vertical cross section of the reactor pressure vessel , consequently with a great effect on the construction costs of the R B. Therefore, the RPV size is minimized by the short fuel length, low pressure loss in the core, low core flow conditions characteristic of an RMWR and by optimizing the chimney height and inside diameter of the chimney. The chimney height of 5.5 m is decisive to maintain the necessary natural circulation head the chimney diameter of 5.4 m is decisive to cause the steam velocity at the chimney exit to be less than 0.7 m s to stabilize the water surface . The height of 2.5 m from the water surface to a main steam line nozzle is adopted to enable a gravitational water steam separation, based on experimental data and a semi-empirical theory . The annulus gap of 1.3 m from the shroud to the RPV is adopted to limit the neutron irradiation rate for the RPV wall and to reduce the carry-under also. As a result, the height of the RPV is about 17.4 m and the diameter about 6.3 m.

X-9 shows plots of cos 6 versus 7l for various series of liquids on Teflon . Each line extrapolates to zero at a certain 7l value, which Zisman has called the critical surface tension 7 since various series extrapolated to about the same value, he proposed that 7 was a quantity characteristic of a given solid. For Teflon, the representative 7 was taken to be about 18 and was regarded as characteristic of a surface consisting of —CF2 — groups.

X-B-2 shows the representation in CRI-MECH of the initial stages of the oxidation of pentane and its linkage with the oxidation of butane. The figures in brackets refer to the number of C— H and C—C bonds in each compound and, therefore, to the maximum number of ozone molecules that can be generated. Each compound name contains a number, which also refers to the maximum number of ozone molecules that can be formed. Thus, pentane contains 4 C—C bonds and 12 C—H bonds and so has an index of 16, as does the peroxy radical formed by H-abstraction, since it still has the potential to form 16 O3 molecules. The index is reduced by one for the peroxy radical formed by subsequent reaction with NO and then O2, since one NO NO2 conversion has occurred. The labeling of the compounds, e.g., RN1602 and CARB13
