Confinement Isolation Project. Nine of
eleven confinement isolation valves have been installed at the Kola
nuclear power plant (NPP). Staff from Burns & Roe are helping with the
installation, which is estimated to take approximately one month.
Brookhaven National Laboratory (BNL) ordered additional gasket material
required to complete the sealing of Kola Unit 2. The material will be
shipped by air to reach the plant before the end of the current outage.
The plant is scheduled to return to operation on May 18, 1996. To
determine how effectively the application of sealant and gasket material
has reduced leakage, the plant intends to perform confinement leak-rate
tests in May. Radiation monitors are another element of the Kola
confinement upgrade effort. The monitors were delivered to the plant the
week of April 8, and the cesium radiation source to be used in calibrating
the monitors is being packaged for shipment. (Rich Denning, PNNL,
Safety Parameter Display Systems for RBMKs.
parsons Power/Gilbert Commonwealth signed a contract with Pacific
Northwest National Laboratory to provide safety parameter display systems
for ten operating RBMK reactors in Russia and Ukraine. The systems are
similar to those being provided to the Kursk NPP Unit 2. Work will begin
immediately to identify plant-specific differences that will affect the
design of the safety parameter display system for each plant. The next
NPP to be provided with a safety parameter display system will be
Chornobyl Unit 3. (Rich Denning, PNNL, 614-424-7412/Rich Reister, DOE,
Kola and Kalinin Full-Scope Simulators. S3
Technologies performed hardware acceptance tests on the Kola and Kalinin
NPP computer complexes on April 3 and 4, 1996, at Columbia, Maryland.
Each computer complex consists of server(s), workstations, personal
computers, and accessories. The tests were largely successful. S3
Technologies is resolving minor problems encountered, which were
associated with a new version of the Irix operating system. In addition,
S3 Technologies staff demonstrated the use of the executive software on
the Kalinin simulation computer (SGI Power Challenge L with four R8000
CPUs). However, the execution of a generic VVER NPP simulator model on
the Kola and Kalinin simulation computers was not successful. S3
Technologies has resolved these problems, and it will not delay either the
project schedule or shipment overseas.
General Energy Technologies
(GET), the simulation model contractor, has requested detailed shipping
invoices from S3 Technologies for the Kola and Kalinin computer complexes
to avoid Customs problems. S3 Technologies is preparing these documents.
Additionally, GET has requested a letter from PNNL to the Agency of
Technical Cooperation with Russia (US Embassy, Moscow) and support from
DOE to have the Agency of Technical Cooperation with Russia send the
necessary letter to the Humanitarian Help Commission in Moscow, Russia.
It is hoped these measures will allow the equipment to flow smoothly
through the Customs process.
Successful completion of the computer
tests and the receipt of Customs related documents will allow the
full-scope simulator computer complexes to be shipped to GET. Once the
equipment is delivered, GET can initiate the development of the actual
simulator models for the Kola and Kalinin NPPs. (Peter Kohut, BNL,
Fuel Cycle Safety. The cask
transporter, which arrived in Ukraine in early January, has been released
from the Customs holding area at the Zaporizhzhya NPP. Duke Engineering
and Services (DE&S) is planning to have people there on Monday, April 22,
to begin inspection of the transporter, to train plant staff in its use,
and to facilitate acceptance of the transporter by the Zaporizhzhya NPP
All remaining DE&S hardware supplied under the DOE contract
has been delivered to the plant and has been put into a Customs holding
area, with the exception of the multi-assembly sealed baskets. DE&S will
try to have the equipment released from Customs while they are at
Zaporizhzhya NPP for transporter acceptance tests. (Mike McKinnon, PNNL,
Khmelnytskyy Full-Scope Simulator. Recently DOE
and Goscomatom signed an agreement to identify the requirements for
obtaining Ukrainian Customs clearance. However, there is more information
required in order for S3 Technologies to obtain release of one unopened
shipment at Energotraining that contains material needed to complete the
control panel modifications at Khmelnytskyy NPP. PNNL has sent the
necessary additional information. (Peter Kohut, BNL, 516-344-4982)

operator training program. (Sonja Haber, BNL, 516-344-3575)
