ISEQUOYAH NUCLEAR PLANT UNITS 1 AND 2 - IE BULLETIN NO. 84-03: REFUELING
- CAVITY WATER SEAL-
- y 10n' August-24,'1984, NRC distributed IE Bulletin 84-03, " Refueling Cavity
. Water Seal" concerning the failure.of a seal at' the Haddam Nuclear Plant.
- .L i TVA responded to that Bulletin on October 2,' 1984.. During a series of
~
conference calls between TVA and NRC on October 15 and 16, your staff expressed concern 'over, the seal' at our Cequoyah Nuclear Plant' with regard
'to the current refueling outage on unit 2.
As a result of that concern, on October?16, 1984 in a. telephone conversation with members of your_ staff, P. = R. Wallace, :Sequoyah Plant Manager, committed to the following:
4
- 1.,0nly_one. irradiated fuel. assembly at a time will be moved inside the reactor cavity. A second irradiated fuel assembly will not be moved
'inside the' reactor cavity until the preceding assembly has been moved
+
ithr'ough the transfer tube-into the Auxiliary Building side of the t
'y transfer canal.'
.T
- 92. -^ The' pocket sump alarm will be used as a symptom of reactor cavity seal l-failure.. Sequoyah will include this mquirement.in its night 'ceders,
_ and operators will be required to myiew the night orders before beginning their shift.
f L
-3 90nce' each shift:we will record the water level in the reactor cavity.
p Please' note that. these measures will be in effect during refueling operations only until the : issue' of cavity seal adequacy is msolved. At that; time,' we will resume our normal refueling operations.
