ENCLOSURE 1 STATEMENT OF WORK-
Title:
Safety Evaluation of Core-Melt Accidents:
Mark - I.BWRs FIN No.: A-3706'
.B&R.No.: 20-19-50-53-3
. Project Manager -: J. Meyer (FTS 492-4752)
Technical Monitors: J. Meyer (FTS 492-9418)
- 5. Acharya (FTS492-4752)/)F. Eltawila (FTS4924645 /J Background and Objective Consideration of severe accidents beyond.the traditional design ' basis', including full core malt accidents, is an important part of NRC's overall safety assessment
- and therefore is becoming an important ingredient in certain specific as well as generic proceedings. Also the consideration of -features to mitigate the consequences of core melt accidents for. nuclear facilities continues to be a major activity. . It is very-imywrteni i. hat ther trege Tniount of_te.chnical information available and being developed by, for example, RES in this area *
. be appropriately assimilated, codified and evaluated in'a way that is directly
- Spplicable to decisional needs. These needs are in three major areas. First,
_ there is a need to better understand the progression of core. melt accident __.
, sequences up to and including associated.coreJnelt_Is. lated phenomenology and.
. the implementation of these processes (and their uncertainties) into an over-
.' all ' assessment of containment loading and failure mo. des. The impact of mit.igation strategies on containment loading and failure modes must also be factored into -
tpeassessment. .
!. Second, based on the containment loading histories, there is a need to determine the radiological source term suspended in the containment, the effects on engineered safety features (E.S.Fs) and mitigation features of this source term and finally l the release charac.teristics of this source term following containment failure.
Third, there is a need f'or an overall capability to assess the radiological con-sequences as a function of the assumptions regarding accident sequences, phenomenology and mitigation hardware. These radiological consequences must be further analyzed
-in a decisional context with a full appreciation of the regulatory implications.
The objective of the activities described in this Statement of Work is to meet
, the above needs.
The scope of this work will be limited to addressing imediate NRR decisional concerns using the stata ,f-the-art codes and the analyses and experimental data developed.from NRC/RES and other R&D programs.
Th'e analyses provided under this contract will help form the basis for positions taken by the staff as required in SECY-82-1B for BWRs with Mark-I containments.
L The program will address all BWR Mark Is. One specific BWR Mark I design and l site will be chosen by the staff at a later date for more detailed assessment.
l "
The extensive analysis and assessment to be performed, code capability to be l developed and' experience to be gained under A-3711 has been taken into account
- in developing this RFP.

STATEMENT OF WORK
Title:
Safety Evaluation of Core-Melt Accidents:
Mark - I BWRs
,, FIN No.: A-3706 B&R No.: 20-19-50-53-3 Project Manager : J. Meyer (FTS 492-4752 -
Technical Monitors: J. Meyer 492-4752 F. Eltawil 492-9418)
S. Acharya(FTS(FTS 492-864 )/J. Mitchehl(F(TS FTS 492-8241 e e Background and Ob.iective Consideratiion of severe accidents beyon'd the traditional design basis, including full core melt accidents, is an important part of NRC's overall safety assessment and therefore is becoming an important ingredient in certain specific as well as generic proceedings. Also the consideration of features to mitigate the consequences of core melt accidents for nuclear facilities continues to be a major activity. It is.very important that the large amount of_te.chnical
'information available and being developed by, for example, RES in this area
., be appropr.iately assimilated, codified and evaluated in a way that is directly -
applicable,to decisional needs. These needs are in three major areas. First,
,, ,- there is a need to better understand the progression.of core. melt accident sequences up to and including associated core melt 2alated phenomenology and the implementation of these processes (and their uncertainties).into an over-all assessment of containment loading and failure mades. The impact of mitigation strategies on containment loading and failure modes.::aust also be factored into .
theassessment.
?..
Second, based on the containment loading histories, there is a need to determine the radiological source term suspended in the containment, the effects on engineered
- safety features (E.S.Fs) and mitigation features of this source term and finally the release charac,teristics of this source term following containment failure.
~
Third' there is a need for an overall capability to assess the radiological con-sequences as a function of the assumptions regarding accident sequences, phenomenology and mitigation hardware. These radiological consequences must be further analyzed in a decisional context with a full appreciation of .the regulatory implications.
The objective of the activities described in this Statement of Work is to meet
, the above needs.
The scope of this work will be limited to addressing imediate NRR decisional concerns using the state-of-the-art codes and the analyses and experimental data
! developed.from NRC/RES and other R&D programs.
I The analyses provided under this an+M "dr BWRs with Mark-I containments."1 help form
! taken by the staff as required E:Y-82-1
! The program will address all BWR Mart . Qne specific BWR Mark I design and site will be chosen by the staff at a ater date for more detailed assessment.
