and theprogram -which emerged ,designated asthe "consensus

The first basic objective oftheconsensus SSTP isthe

The contractiong Parties hereby set up .aBilateral Technical
Implamentation Committee toassure theexecution ofthe
co-operation pi/ovided for .inthis Arrangement .
Each Party will designate itsmembers tothis Bilateral
Cor.imittae .andmay further designate atechnical spokesman .
-.The Committee shall meet atleast annually toreview SSTprogramme
progress and the effectiveness ofthecooperative programme effort
The output from these meetings will beused bytheNRC»as apart
ofits annual internal review ofthe SSTprogramme progress and /
itscontinued .applicability tocurrent NRC programme objectives ."

■IX
AM Vi'A .II
The basic USNRC in-kino cjiit.ribution shall beatanannual level roughly
equivalent to1,500,000 US1981 dollars ormore ,(subject tocontinued
annual UScongressional funding ofprogramme support and maintenance of
SSTprogramme content andprogress )asdefined inART .6oftheArrangement .
The form ofthe UScontribution ,listed inorder ofpriority ,shall be :
1.NRC basic supply of3test trains including ill precalculations ,R&D ,
operational data ,safety analyses ,QA-QC results ,inaddition tothe
test train hardware and components for tests and schedules equivalent
toorbetter than SFDA-1 ,SFDB-1 and SFDC-1 ofthe currently planned •
SST programme ,subject toUScash flow limitations .
2.Long term assignments providing liaison with PNL toassist Ispra in s
2.1 .harmonizing with USprecalculations and test operational specifications ;
ι
2.2 .harmonizing with USdesign and analysis ofSFD-TT 's;
,2.3 .assembly ofSFD-TT 'satIspra ;
2.4 .SFD test feasibility and safety assessment ;
2.5 .co-ordination ofPBF test experiment and results (e.g. shroud
performance )into Super-SARA planning .
3.Short term assignments providing : ■
3.1 .assistance with loop commissioning activities ;
3.2 .specification and development ofspecial software for data
-acquisition system and programme monitoring system ;
3.3 .assistance incalibration and application ofthe transient thermo­
hydraulic instrumentation ;
3.4 .assistance indesign ,testing andapplication ofthetransient rodsystem
3.5 .assistance inthe fission product release (FPR )field ,with aview to
attaining optimal specifications for theSuper-SARA FPRmonitoring
system inthe light ofUSexperience with similar ecmipment .
4.Supporting services inthe US :
4.J.,special analyses ,defined and requested by.Ispra and agreed toby
NRC ,tosupport ;
s
4,2 .back-up for item 2abovej '
4.2 .1-.safety assessment ; v
S
4.2.2 .test precalculations performed byIspra .

2.
5.Supply ofspecial components for remaining test trains *
B.l .advanced instrumentation ,e.g .:'
5.1.1 .fused alloy high temperature sensors ;
5.1.2 .mixture level sensors ;
5.1.3 ..11shrouds . *' '
The annual NRC level ofSSTP support effort for the several listed
activities ,isestimated asfollows :
'. i
item 2:oneman peryear for 5years ;
item 3:eight man months per year for 3years ;
item 4:seven man years . . _
The U.SNRC notes that atthe' minimum level ofin-kind contribution of
,dlr .1.5m/year there ishigh risk that delivery ofthethree test trains
may notbetimely .NRC budget projections donot allow for initial annual
in-kind contributions ofmore than dir .1.5m thus ,thepriority schedule
mayneed periodic examination and revision toreflect these limitations .
TheNRC notes further t,hat total funding will probably not cover more
than asmall part ofthevitem 5priorities ,e.g. the 11shrouds initem
5.1.3 .probably cannot beprovided ,either inatimely fashion' or ,
within theavailable annual NRC 1funding levels . .
