V. V. Kroeov]
[Text] The fourCh yeAr of Che Tenth Five-Year Pl~n ia an importanr stage
along Che road toward itis auccessful completion. Zo acnieve Chis, it is ~
necessary to raise the level of labor organization, and the intensity and
pace of work in sll labor units af Che induatry, and to concentrate the ef-
forts and means on the main directions. If in this connection we turn to -
the goals se~ for our secCor of. industry by the "Guidelines for the Develop-
_ m~nC af the National Economy of the USSR for 1976-1980," it ia posaible to
say Chad moar of them are being consiatently achieved. Production associa-
tions and enterprises of the ministry are achieving the main indexea of the
State Plan for Economic and Social Development: che pace of growth, i~,crease
of the production volume, and incr~ase in labor productivity. This ia ex-
pressed c~ncretely in further equipment of domestic electric power engineer-
ing, gas industry, and other sectors of the national economy with modern,
reliable equipment.
ParCicipating directly in solving the problems poaed by the development of
the fuel and energy complex of the country, production asaociations and enter-
prises of our industry have created a complete set of Chermomechanical equip-
ment for an energy unit of 1200 MW which will be inatalled at Koatromekaya
GRES. The firat custom-made hydraulic unit of 640 MW for the world's largest
Sayano-Shushenskaya GES has been delivered. The production of Che second
unit is nearing completion. The delivery of equipment for hydroelectric
power stations which are under construction in Siberia and in ~he Ear East
is also nearing completion: for Uat'-Ilimekay GES and Zeyakaya GES, as well
as for the Central Asiatic Nurekskaya GES. Power units have bpen manufao-
- tured for the new blocks of Leningradskaya, Rurakaya, and Chernobyl'skaya
AES; equipment of the ffrat unit with a water-moderated water-cooled reactor
of 1000 MW which will be inatalled at Novovoronezhskaya AES.
Designera and technologists of our industry invested much work, creative
energy, and knowledge into the creation of thia unique unit.

In the course of tl~e rhree years of Che Tenth ~ive-Year Plai~, oiir industry
has been reconaCructing ~nd reequipping the opernting enterprises attd ~vns
sCeudily incrensing the output of power equipment, primurLly for ttComic elec-

socialisC competiCion and concentrated their efforts and creative energy on
the fu1fi11menC und overfu1fi11menC of Che planned gonls. The producCion
_ association "Krnsnyy koCel'shchik" orggnized a campaign for on-time produc-
tion and high quality of ateam generators and heaC-exchunge equipmenC and
initiated a compeCition under the slogan "eo work without lagging workera".
This iniCiaCive of Taganro~ boiler manufACturers was supported by Che Ministry
Board and Preaidium of the Central Committee of the industry's trude union, _
Taganrog city committee and Rostovskaya flblasC cortunittee of the party. On
16 April 1977, "PravdA" newspaper published a letter of the Secretary Ceneral
of the CPSU Central Committee Comrade L. I. Brezhnev to ttie workers of Che
Don area in which he stresaed the importance of the campaign "To worlc with-
out lagging workers" for the country and for the fulfillment of the goals of
the national economy. An All-Union conference-seminar was tield in Roatov to
discuss Chis effective trend in socialist competitions. It muat become one
of the guidelines in labor competiCions umong the collectives of our indusCry :
in the fourth year of the Tenth Five-Year Plan in conformity with special
characteristics of production and conditiona of each enterpriae.
Production associations "Leningradskiy r~~tallicheakiy zavod", "Izhorakiy za-

- oC the rtvers in ttie central part of the country and the increasing construc-
tion of AES and ATETs [ato?nic heat and electric power stations]. In order to
- increase the effectiveness of the use of solid fuel of the eustern regions,
it is necessary to build highly productive boiler units with new merhods of ~
coal burning and achieve an increase in the unit power of units, which pro-
mises great savings in metals an~i operational expenses. �
~ne oE the immediate problems of our industry in the Tenth Five-Year Plan is
. further increase of the output of equipment for atomic electric power stations.
To ensure its fulfillment, we must, by the end oF the five-year plan, to cre-
ate complex capacities necessary ior the production outpur in the volumes set
_ hy the Cuidlines for Che Development of the National Economy of the USSR for
1976-1980. The real way of accomplishing this is: acceleration of tt~e pace
of construction of "Atommash" and installation of equipment at the prepared
construction sites, creation of capacities in the production association "Izh- ~
orskLy zavad" imeni A. A. Zhdanov, as well as ae a number of orher enterprises
participating in the production of equipmenC for AES. The USSR Gosplan has -
; not yet produced such plans for the latter, and this could hinder the develop-
ment of power engineering and the utilization of capacities already cre~ted
in the country. In the production assccir~tion "Izhorskiy zavod" imenL A. A,
Zhdanov, in 1979, we must complete the reconstruction of the sl~op manufactur- '

Just as before, ocie of the most important problems is thc problem of uninter-
rupted supply of heat to the population and enterprises of. various sectors of

Our industry hus been entrusCed with khe anlvin~ of anoeher problem whicl~ is _
very in?portant for the nAtional economy; tio develop the production of diesel
engines for qu~rry dump trucks and other l~rge Crucka. The designers of the

signed and teated engines ChN6 21/21 and ChN8 21/21, Production workers have
eo seC up their production in rhe shorteat poasible tim~ and in Che required

Co puC its firsC secCion inCo operation no later Chan 1980. This will make ~
it possible to starC the producrion of the engines which are necessary Eor
Che national economy at Che beginning of the next five-year plan,
In the rhree years, we were able, Co a certain degree, to replace our fixed
c.apital, Co obtain and install new rechnological equipmenC, and ro raise the
level of production sCandards and organizaCion. This makes it possible ~o
solve the main problem: to increase the producCion volume oF high-quality
power equipment. During the fourth year, our industry will not only continue
t}iis important work, but will also strive for its acceleraCion by c~ll posei-
ble means at all enterprises of the industry without exception.
_ It is also necess3ry to conCinue the development and improvement of rhe �acil-
~ itt~s for the production of unfinished articles, to use their existing capac-
ities more fully, and to supply rational billets to the industry, which
will reduce rhe consumption of ineCal and labor input in the production. E~r
the production association "Izhorskiy zavod" imeni A. A. Zhdanov and at the
: Kramatorsk Casting and Forging P1anC, modern eyuipment was installed for oh-
; taining high-quality steel and alloys of various classes. However, theae
~ capacities are not used to the fullesr.. The main cause is the fact that
when designers create new power zquipment and modernize the equipment which
_ , is in production they rarely use particularly pure metals with higher mech-
- anical properties and service characteristics in their designs.
- The associations and enterprises of our industry acquired a large amount of
' domestic and foreign wtlding equipment in recent years, however, its adjust-
ment is unj~istifiably delayed and it is not used effectively. The quality of
welding in the industry still remains to be one of the most important problems,
- therefore, speedy introduction of new welding equipment will considerably
accelerate t:~e production of power eyuipmenti and improve its quality.

One of the main tasks of every work team of our industry in its competition
for improving the effectiveness and quality of work in the fourth year of the ~
Tenth Five-Year Plan is economical use of material and t~chnical resoUrces,
primarily, metals, electric energy, heAC, and fuel. All enterprises must

fective me3sures for Cheir rational and most effective involvement in produc-
tion. Unfinished production has to be thoroughly analyzed and its poten-

[Text] Tn accordance with the decision of the parCy, the Sayanskiy territo-
_ rial production complex is being created in the south oF Krasnoyarskiy Kray.
Its energy basis will be the Sayano-Shushenskaya GES with an inaCalled capac-
- ity of 6400 MW. The Sayano-Shushenskaya GES is being built on Che Yenisey
River in the narrow Karlov Stvor not far f rom Shushenskoye, th~ place of ~
V. I. Lenin's Siberian exile. ~
The Sayano-Shuahenskaya GESis the world'slargest hydraulic development which
is unique in size and complexity. Nine million cubic meters of concrete will
be poured into a 24 5 m high dam. The spillway structures are designed for
leCting through and suppressing high water flow rates: 13,600 m3/aec. The
annual ouCpur of electric energy will be 23.5 billion kWh. The hydroturbine !
equipment for the Sayano-Shushenakaya GES was developed for the following
conditiona:
- Head in meters:
max imum 220
rated 194
minimum 175
A turbine with a rated power of 650 MW, with a wheel diameter D1 = 6.77 m,
and rotarion frequency n= 142.8 rpm has been developed. Its maximum ef- -
ficiency is about 9 6%. At a head of 212 m and higher, rhe hydroturbine is
capable of attaining its maximum power of 735 MW.
A~cording to the design assignment of the Minenergo [Ministry of Power and
Electrfficationj, the iniCial power of the turbine was set at 540 MW.

The production ~sadci~Cion oF Curbine building "Leningrad Metal Planr" ex- -
~ amined the possibility and practicaltCy of creaCing a turbine wiCh a uni.t ,
- cupacity of 540-1500 MW for the condiCiona or the Sayano-Shushenekaya GES.
Studies sl~owed rhe technicttl poeaibiliCy oF creating a high-power turbine.
Power machine builders proposed to equip this GE5 with turbinea of $15 MW.
Ay the complex of the technical and economic inrlexes of rhis G~S as a whole,
it was found Chat the power of 650 riW was optimal.
Ir was possible ro increase the power of Che Curbine to 650 MW without chang- -
- ing rhe dimensions o� a 540 MW machine by increasing its speed of operaCion,
which made it possible to reduce the number of units from 12 ro 10, to obtain
a noticeable economic effecC, and to lay out the enCire hydraulic development
more raCionally, In the narrow passage of the GES, in ~he presenc~e ~f 12
_ units, the spillway was located above Che GES builc~ing, as a result of which
Chere was no reliable suppression of energy of the efFluent water. By re-
_ ducing Che number of units, it was possible ro place the spillwAy next Co Che
GES building,
The developed wheels make it possible ta begin the operation of Che Curbines
wiCh a head of 120 m. The first two turbines are equipped wiCh replaceable
_ wheels capable of working aC Che heads of 60-140 m and to develop the power
of. 150-400 MW. This makes it possible to increase the effectiveness of cap-
ital investments by pukting the units into operation while the conatrucCion
of the dam is nat yet completed. During the operaCion of the units with re-
' placeable wheels at the heads of 60-140 m and units wirh standard wheels ul�
lower heads of 120-175 m, additional 16 billion kWh o~ electric energy wi11
be produced.
The hydroturbine equipment for the Sayano-Shushenskaya ~ES developed wiCh
consideration for the latest achievements of Soviet and world hydroturbine
building on the basis of complex scientific research an~ technological de-
sign studies has marked a new step in the development of Soviet hydroCurbine
building. Many fundamentai design and technological "Sayan" solutions have
become basic standard solutions of the association and the industry.
The hydroturbine equipment ~~as created in close cooperation with many insti-
tutes, associations, and plants of the Soviet Union and, primarily, with the
Gidroproyekt [All-Union Planning, Surveying, and Scientific Reaearch Insti- -

transporting of the coal from the longwalls to the inclined drifts driven on
the boundaries of the central aection= the drifts here are overworked. Then
the xorking faces begin to be serviced by those excavation drifts that pre-
viously xere driven in the central section. Consequently, the plan guarantees ~
rapid aervicing of the longxalls by the incline.d drifts and excavation drifts '
(at .first xing, then central) = the ehange of functions of the inclined ~
drifts is also guarantsed (for servicing first the woxking faces, then the '
preparatory) ~ These drifts made on the boundaries of the central section are
eliminated by the sections after their overworking, at the end of which ~
driving of the excavation drifts begins. In order to ventilate the longwalls
and drifts additional single inclined drifts are made that are eliminated
as the levels are xorked off, as a result of xhich the plan can be employed
also on dsep shafts.
The pla,n makes it possible to completely solve five of the first taain problems
and partially the sixth. Plan 4 is designed only for new shafts with great
(8 km and over) length of the shaft field xith respect to extent on the non- ~
blox-out-dangerous beds~ as xell as on the blow-out-dangerous~ preliminarily ~
diacharged or with angle of incidence less than 10~. Ir. the given case the
movement of the sfi.ream of air coming from the working faces is dascendingi
xith ascending movement the plan can also be used on blow-out-dangerous beds~

(Article by S. M. D~nelyanee, A. A. Loginov, and A. A. Chernik: "Bit for
thilling CemenC ~luge"
(TexC~ CemenC plug drilling ie a crlCical operation which completes the
well construction cycle. This operaeion frequenCly ende in hard-to-repair
breakdowng, such as breaking of drill pipe. The main difficuley in repair-
ing Che consequences of auch occurrenceg lies in the impoeeibility of either
wiChdrawing the dxill bit or destroying it during eubaequent drilling due
to the high strength of the materials from which bit componenea are manufac-
tured. As a result it is necesaary to drill a new borehale section, and
this involvea considerable time and money. -
