B. Visit to the Construction Site
1. Location
50X1-HUM
An auto ride of about 150 km from Chongjin (the harbor
where the parts will arrive) along the coast to Unggi
50X1-HUM
along a poor secondary road which
presumably follows the path along which the Unggi-Aoji rail line
will be laid. (See the overlay
The building, site is in a valley several dozen kilometers
from the China/Korea/USSR corner of Korea, near the village of
Aojidong. Location on map NI 52-6 (1:250,000) and PC 290B
(1:500,000): 1300 2241, 42? 31'N.
The building site is part of a Kombinat (exact name un-
known) that lies in the middle of a coal bearing mountain area.
2. Description
a. Coal Processing
The coal is mined in the area of the Kombinat. The
coal is broken, screened and washed; after "Schwellung" to half-
cokes whereby tar is separated. The tar is processed into
naphthaline, creosote and pitch (no benzene). In front of the
warehouse is a separate tank park with many small tanks.
The halfcokes were broken and screened to a pellet
size of 5 um and vaporize* in a continuous winkler vaporizor with
oxygen (capacity 20,000 ma per hour). The vaporizing was expanded
to 40,000 ma per hour (fanned with 02 enriched air). They pika to
expand the output another 40,000 me per hour in the future. The
CO2 rich gas goes in due course via an 1128 extraction process and
a (with sodium arsenaal active) desulpherization installation to
a gas container.

Iour tile gas tana later a part of he gas) goes to
a CO2 conversion (compressed to 240 atm.), to methanol synthesis.

After which it is rectified in a very tall thin column to Imre
methanol. 50X1-HUM
b. Air Separation Installation
There is a very old air separation installation in the
Kombinat built by the Japanese in 1930. The installation was 50X1-HUM
repeatedly destroyed by American and Japanese bombing, but was
rebuilt. The whole thing is very old fashioned, and
won't last such longer. Pressure: 200 atm ifirst
axial blowers, afterwards pure). Capacity: 5x1500 mJ/hour. 50X1-HUM
There are five units, three of them in action, one in reserve
and one being repaired. Much copper and brass, but the copper
welding work is poor quality.
c. NH3 Synthesis
There is an 1(113 synthesis in addition, built around
the existing synthesis columns (that apparently survived the war).
Quality of the apparatus and the welding is vary unsstisfactory.
The high pressure connections will cause 50X1-HUM
difficulties.
ad, Ammonium nitrate is produced from a supply of nitric
acid. The mechanical maintenance of this installation was very
good, the valves and bearings looked good.
d. Workplace for Apparatus Building
good welding machines in this work place,
but which had not been used such. The cables are bad, coupling
pieces missing, joints in the cables were insola ted with
pieces of jute and cardboara?Fromr---]superficial observa-
tion, the welding appeared good, but had many welding faults 50X1-HUM
(unsatisfactory welding). Rustfree steel welding and argon-arc
welding were unknown.

e. A Mechanical Work Place
This looked good; there was good equipment.
f. An Zlectric Power Plant
There is a power plant (that pill provide current and
condensaat); an open-air high-tension station. The high-tension
feed is triangular connection. neirmal 3.3 KV the maximum short
circuit current is 74 U. in the 3 KV net; the
maiiinum short circuit capacity carries 150 50X1-FIUN
MVA. Voltages were not recorded During the
dry months the voltage drops to 3 KV. It will be necessary to
check on whether this can carry the HS-motors which will be 50X1-HUM

.installed in the plant (the low current falls with the weather).
The low voltage carries 400 volts with 3.3 KV, with 3 KV the
voltages will still be sufficient (about 360 volts).
Urea Plant
This will not be built on the land of the Kobinat,
but on the other side of a bordering stream, across from the high-
tension power station. The prills will be transported on a belt
transporter along the stream to a spur-line which is to be built
from Unggi. The station installation will include offices, ware-
houses, prill storage sheds and loading platforms.
50X1-HUM
The materials for the installation will come from
the harbor at Chongjin by spur-line to Aoji. Thus, the spur-
line must be completed in order for the construction of the plant
to begin.-the right of way of the new spur-line 50X1-HUM
from Aoji In some paces the tracks had been laid (with electric
overhead lines), in other places the foundation wassail under
construction. doubt?lthat the spur-line would be in
operation in time.
C. Discussion of the Preliminary Project
50X1-HUM
50X1-HUM
50X1-HUM
1. Organization of the construction staff, composition of
the supervisory team, the construction plan, and the estimated
man hours were discussed and accepted
a A promise was received that 1/3 of the total number-of 50X1-HUM
Koreans employed in the construction would be trained specialists,
1/3 seni-trained and 1/3 un-trained.
2.
The installa-
tion should begin and thus the civil ongineoring50X1-HUM
work must be completed by that time.
3. Welding Rustfree Steel
eldere must be selected and training STAT
in argon-arc must be begun. Argon-arc equipment, rustfree steel
equipment, portable X-ray equipment (including film) and pipe
bending machines were not available. Brochures (with price data)
have been requested in order thet procurement
can be considered. Argon-gas is available, composed of 15% to 50X1-HUM
20% nitrogen, however, Client requested s statement of needed
amounts and desired composition of argon-gas and formiergas
4. Possibility for Expanding the Plant
It was requested that the planning include a lengthened

compressor room so that additional 'compressors might be installed.
5. Air
There is clean dry air of 5 atm. present. For large
electrical disturbance bottiesof nitrogen (100-120
atm.) would be built in the plant. The company will,
therefore, deliver reduction valves (two step).
6. Civil Work
50X1-HUM
OUA I -mum
50X1-HUM
The building in the Kombinat were very
old and repeatedly rebuilt (after the bombings),
iconcrete or steel construction with brick filling., mostly very
door. Therefore, requested precise details on the new
buildings. The skeleton would be prefabricated concrete (as in
the WSW, the walls brick masonry, and both sides plastered. A
part of the walls would be closed off with prefabricated concrete
plates. In any event, the roofs and floors would be of pre-
fabricated concrete plates. In places where heavy apparatus will
be placed, a strong floor would be built. Light construction
would not have deep foundations. For the heavy, there is a weight
bearing layer (115 tons/cubic meter) about 6 meters deep. It
is not yet decided whether to dig so deep, perhaps only for the
compressors and the prill towers. The upper layer is llialallk
Min dry weather, very hard and cracked, in rainy weather, very
slippery and not porous. Appears reddish and clay-like 4011161.040,
Below this layer is disintegrated rocks. The electric cables
would be placed in conduits in the disintegrated rock soil. The
soil would be loosened with mattocks.

In connection with the expected costs
client requested blueprints and studies as soon as possible,
not to wait for definitive drawings to be completed.

7. Material Transport
the station emplace- 50X1-HUM
sent will be completed along a good road. They have had some
experience with hoisting of autoclaves, but 50X1-HUM
instruction on hoisting.was rev:fisted.
8. FinaProtection
No special fire protection, no sprinklers. Aside from
a normal amount of hydrants and hoses, on each floor there will
be some dry extinguishers. rrr?r-T
