Proposed Changes to Original Exam Answer Key J
Comment Q49: Answer D was listed in the key as being the correct answer. C is also correct based on the fact that Fermi 2 has a Mark 1 Containment. The Mark 1 Containment is susceptible to the phenomenon know as CHUGGING.
See Appendix B, Rev 2 of the EPGs, Page 8-7-35, for additional information regarding the following:
Following a DBA LOCA, Drywell Pressure (DW/P) would rapidly increase and force steam and non-condensable gasses from the Drywell into the Torus.
Torus Pressure would rapidly rise and exceed the Suppression Spray Initiation Pressure (SCIP), which is 9 psig for Fermi 2. Once the Torus Pressure exceeds 9 psig, the EPGs assume that a large fraction (95%) of the non-condensable gasses (nitrogen inerting the drywell) in the Drywell have been transferred to the Torus. Once this occurs, chugging becomes a primary concern.
Chugging is defined as: the repeated collapsing, and reformation, of steam bubbles at the Downcomer Vent opening. When the steam bubbles collapse at the exit of the Downcomers. the rush of water drawn into the Downcomer, to fill the void, induces severe stresses at the junction of the Downcomers and Vent Header in the Mark 1 Containments. Repeated application of such stresses could cause fatigue failure of these joints, thereby creating a direct path between the Drywell and Suppression Chamber. Steam discharged through the Downcomers could then bypass the Suppression Pool and directly pressurize the Primary Containment.
Initiating Drywell Sprays when Torus Pressure exceeds 9 psig, will cause the non-condensable gasses to be drawn back into the Drywell atmosphere, thereby preventing chugging.
With Drywell Sprays not available, (as stated in distractor C) chugging could not be prevented and containment integrity could be threatened, as described in the EPGs.
Therefore we recommend both answers be accepted.
Comment (263: Answer D was listed in the key as being the correct answer. C is also correct The term reason led the examinees to not look for the basis of the Main Steam Tunnel High Temperature Auto Isolation. The stem should have stated the auto isolation and the basis per 10CFRl00. This allowed Answer C to also be correct. Answer C is a reason to isolate MSIVs. This question originally had basis, instead of reason, in the stem. It was changed upon NRC request.
The Secondary Containment and Radioactive Release EOP purposelbasis is to protect equipment important to safety, in the Secondary Containment, to protect the integrity of the Secondary Containment, and to limit radioactivity release to and from the Secondary Containment. See attached information from SCClRR EOP Student Text.
Therefore we recommend both answers be accepted.
