AGE 30A October 18-19, 1938 TMI-1 PLANT. VISIT Concerns and Questions 1.
We will want to validate the time estimates in the PRA for time duration required to take ramoto (local control) actions for recovery or mitigation 1
HAM 2, HCV1, E V7, EEF1, M 2, W 3. IUfLIB, BRE4, HRE12, HTC1, HVB1:
and the feasibility of sequences HKR1, ESR1, HRE4, ERE6.
2.
We will w. int te inquire about The basis for the 2-hr battery life assumption upon loss of a.
all ael b.
The basis for the apparent assumption (?) in the PRA that the steam tuibino driven auxilitry feedwater pump can be manually operated upon loss of all ACLand Dc; Whether the loss of control building ventilation will lead to c.
corn melt d.
Whether loss of Ac bus does not trip the plants Why loss of DC bus A is an initiator but not DC tra 33 e.
f.
ht the adhinistrative limits and best estimates are for transient combustibles in the fire areas or zones:
3 h t the fire detection and suppression systens are in each area we visit; l
i h.
Cennrally where cable wrapping and water walla vs.s added to comply with Appendix R, and were there any major exceptions taken to Appendix R1 1.
Do they know what guidelines were used in the PRA to
. determine the geometric factors, severity factors and nonsuppression factors in the fire analysisi j.
How would they recover the nucisar servlees river water when the acreens are plugged:
k.
Et are the cooling requirements (HVA'C or coolirt water) for APWS and HPI motor-driven pumps:
J
~
We believe ths.t we must be escorted and accompanied by a GPU PRA analyst, pref trably someone who is familiar with the FRA. We would like to M sit the following areas:
- a. A7W pump room (s):
- b. Diesel gene.rator room (s);
- c. Battery roca(s):
- d. Service water systems
- e. ECCS pumps and trains;
- f. Cable spreading room and electrical rooms near control room;
- g. Control roce (look into);
- h. 480 Vac and 4160 Vac emergency switchgaar rooms;
- i. Nuc*4ene services river water intake structures J. HPI pumps
- k. Wucient services closed cooling water pumps;
- 1. CBV system fans and dampers 4
