Oil COLLECTION SYSTEM REACTOR COOLANT PL41PS, FLOR 10A F0WER AND LIGHT Col:PANY ST. LUCIE 2 - DOCKET NO.
50 389 FROM J. OLSHINSKI TO 0. E15ENHtli By acr orandum, dated Itarch 15, 1983, Region !! requested the NRC position on the capacity of the container required by Section !!!.0 of Appendix R to "hold the entire lube oli system inventory."
section !!!.0 Oil Collection Systems for Reactor Coolant Pump is written for a single pump.
Therefore if there is only one reactor coolant pump, the container is requiied to hold the entire inventory of the oil system of the pump.
If additional pumps are present they would each be provided with a separate collection container.
There are usuall," frem 2 to 4 pumps in a plant.
Because the oil inve.ntory of one large pump is approximately 275 gallons; some licensees have provided several containers connected in parallel for each pump.
l
]
In seme cases licensect have provided one container to which all pumps 1
would drain '. hat has the capacity to hold the oil from one pump's oil system with a margin.
k's find this acceptable if it is located wit.hin the containeent such that if the container overflows (due to draining
)
from more than one pump) the oil p'iesents no threat to safety ccmponents i
I within the containment or to the plants capability to cepe with other design basis events.
In stmary, the NRC staff pa) tion on the Capacity of reactor coolant pump oil collection system which meets our guidelines and Section !!!.0 of Appendix R to 10 CFR 50 is as follows:
1 1.
One or more tanks n(ed to be provided with sufficient catacity to collect the total icbe oil inwentory from all rcector coolant pumps draining to the container; or i
i 2.
1 One or eore tanks need to be provided with suf ficient capacity to hold the total lube oil inventory of one reactor coolant tv p with i
margin if the tank (s) are incated such that any overflow from the 3
tanL(s) will be drained to a safe location where the lube oil
{
will not present an emposure fire hazard to or otherwise endanger safety related equ'pment; or 4

Darrell G. Eisenhut,
3.
Where the RCP lube oil system is shown to be capaple of withstanding the safe shutdown earthquake ($$E), the container site i<hich satisfies 2 auve is hemed acceptable to protect only egainst possible leak-age due to ranoom leaks in the lube oil system.
For those pumps where the lube oil is contained entirely within the pump
{
casing, an oil collection system may not be required and an exemption to Section 11,1.0 a.ay be granted.
This position applies to all plants with oil collection systems for reactor s
J coolant putps; therefore, all kegions should be informed.
