Th managementand staffof COE,NEK, Bnegoproekt, the Committeefor PeacefulUses of AtomicEnergy, and EQE-International,actively paicipated in the work of the mission. The first draft of the studywas prepaed in March 1993.based on the findingsof the mission. The draft wasdicussed withthe Bulgaria authoritiesin March/April1993. Followingthese discussions,the studywas revised. The data on costs for saoftyupgrades at tie nuclearunis used in th report were provided by NEK with the assistance of otie consultants. They differ somewhat from the nuclear safetycost dataused In the SummaryReport psented to th G-7,which were provided later by EBRD. The differences,however, are not large and do not affectthe overl conclusions.

This study b specifically of the atative ergy sources in Bulgar, whih has 4 VVER 440 model 230 nucear unit (uni 1-4), at Its Kozody nula plat with 1760 MW of go gent caacity. Tleb unit repnt about 1S% of Bugriaas g capacity, but typically 20-25% of generation, sinc they ae b load units. Kozloduyalo has 2 VVER 1000 nudea uni (uni S and 6), each with 1000MW of geneatingcapacity representing an additional17% of capacity. This repot ams that any nuciear power unakwhich condties to operat over an extendedperiod, undertk ma or Wivesme to upgade nuclr saft. The report then ass alt tivo detricity supply option and their associatedcosts if Bulgariawe tD shut dow some or all of its nuclearpower iits under variousacceleated meles stead of underking thes major nuclear safety upgrades. The feasibility of ealy cosure of ths nudea plant b dendt on th abffityof Bulgra tW: (1) obta reliable and econDomicenergy supplies (most o which wud be Impoted) to metd fhti demand_ (2) finance internally or obtain extera financingfor te investmentsin nuclear saety and non-nucea generatingunits which would be required; and (3) managethe shon lead tm requird for iestment selection, financingaragement, design and constuction. t is also dependenton the countrys willingnessto pay the costs ivolved in nuclear sfety upgrades and replacementof nuclear power by alatives. Six nuclearelecticity supplyscenaios, scenarios0 to 5, were developedby tie Bulgaian Govenment for adysis purpoes. lhe scenariosrange from shuttingdown all nuclear units incuding the VVER 1000sImmiately (sio 0) tO nning all unit to the and of their design lives after safety upgradng (sceao 5). The other scnarios, 14, are In betweenand invole vaous closu dates for the 4 VVER 440s rging from closing all 4 of these units I ditely, but coning to rtn the VVER 100s to the nd of ther design lives after safety upgrades (sc io 1), to closiog units 1 and 2 in 1998 and saowing udts 3 and 4, as well as the VVER 1000sto contie operat to the end of their design lives after safety upgrades (scenarIo4). Also, three electricitydemand foreasts for the period 1993 to 2010 (minmum, medium and maxim) were agreed between the Bugariwn Govenet, the Bank and the IMA. e mediumfoes is generallyused by the BulgarianGovrnent for its planning puroe while the minmum or low forecast, which assumesconsiderable demand sde management,is based prmariy on work done by the Bank The maximumor high case was agreed upon as an upper limit The six nuclear supply scenaios coubined with the tee demand forecasts create 18 possible cas, for each of which a least cost electricity supply plan was developed. The main conclusios fom the analysis are: (1) it does not appear to be eoonomically feasibleto close the VVER 1000 units at Koloduy (the safer unis) ough these shoid underg ay upgradin, (2) the least cost electricitysupply option for Bulgariais to run all of the nuclearunits tohe end of their designlives after safety upgrading;(3) it would be tecdnicallyfeaible for Bulgada to teplace som or arl of the VVER 440s (the less safe unit) with alteative electricitysupplies and ene sving mueasm-sby the mid to late 1990s; (4) there are several relativelylow cost eletricity sly alternives in Bulgada the most important of which is probably use of highly efficient gs-fired combined cycle generatin uni espcay in existing dis'rlct heatng ad industrial generting plants; nd (5) the addion cost of replacigfthe VVER
