I failure may occur, the noble gases would be transported out of the primary system by steam flow and would become airborne withi: the primary containmen:

of a PWR (or withi: the drywell of a 3WR).

Some frac: ion of the iodines and less volatile fission products that are released as a result of fuel rod i

failure would also be ::ansported out of the primary system by the steam flow and bec:me airborne, and some fraction would remain in solution in_the sump water or would be deposited on surfaces withi: the pri=ary system.

The amous that becomes airborne outside :he primary system would be strongly depende::

\\

l on the time of fuel red failure and the ::ansport phenomenon for each species within the primary system.

Followi=g the release f rom the primary system, the fission products would be distribu:ed wi:hin the coc:ainment.

For a PWR contaia=ect, the released airborne activity would rapidly disperse and become uniformly dis::ibuted 1

w ::i: :he primary con:ainment.

For a SWR, the released activity would be airborne withi: the drywell.

Following ini:ial release to -he coc:ainmen 2:mosphere. :he action of natural :envec:ica :urrents and IST equipment, such as :coling fans will cause time-dependen: redistributis: Of :he ac:ivity w :hi

addi: ion, there could be some deposition acd plateout of radioac:ivity (iodice and daughters of noble gases) on surfaces of ductwork or on the walls of

secondary containment.

During the longer term, contaminated primary coolant could be circulated through pipes outside of containment (pWR residual heat removal model).

The staff usually assumes a failure of a seal in the ECCS equipment, such : hat significac: quacti:ies of coolant could leak into compartments outside of con ainment.

The leaked fluid is either re:ained in a sealed room or ransported to the radwas e system.

Some porti:n of :his leaked fluid is volatilized and also ::ansported in :he air of ::ese c:mpartmen:3.

These sources would be processed to some exces; by ESF fil:ers.

Thus, a given piece o f equip.nen; ma'/ receive a dose c ::::buti:n i

guidance required a number of assu=ptions to be made regarding :he time-dependent behavior of material wi;his and outside of containment, -he staff, in this report, has performed an analysis of the radiation environmen: that is associated with the source term of position C.2 of Regulation Guide 1. 39,

~

using assumptions and methods which were intended to be consistent wi:h staff practices in analyzing the radiological consequences of a design basis LOCA.

Position C.2 of Regulatory Guide 1,39 assumes a source term condition i

associated with a core mel:down.

To get a feel for the degree of conserratism in :his assumption, calculations using the RELA?-EM (Evalua-ion Model) program, wnich uses the conservacive assumptions given in Appendix X to 10 CTR Part 50, predic: ::a: :he peak cladding :empera:ure attained by the hottes fuel rod will be less than 2000*F.

Based on the predicted distribution of cladding temperature -troughout the core, it is estimated : hat between 20 and 30 percen:

of the fuel rods could experience cladding failure for a.:WR with a lesser fraction for a 3WR.

Calculations performed using the more realistic RI*A?,

(3es: Is imate) program predicted much lower cladding :eepers ::es than RE LA? -EM.

3ased on the RELAP-SI predictio s, the number of fuel rod cladding failures is estima ed to be less han 10 perce:0, e
