pcs.crJption rlf NnncompU.L111c.e.:ind On July 2, 1980 nt 1700 hour0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br />.s, a welded scam on the Gcnerntor Seal Oil Strainer. bun:;t result fog in n major loss of oil to the turbine buil_ding *floor.
Due to the. Hydrogen concentrati~n in the generator
. at that titile, the oil system could not be shutdown until the unit was.shutdown and thoroughly purged with carbon dioxide~
The Hydrogen con~e:ntration was less than 3% at 2200 hou_rs on 7 /2/80 and _the oil
- system ~as shutdown*nt that time.
During this five hour period,*
approximately 10,000 gallons of lubricating oii was spilt onto.the floor*.
. The. 'immediate :action taken by members of the plant staff, Operations, Mai~tenance, a~d Chemistry was to:
- 1) build dams(t1sing clay based oil* absorba~t) to prevent. oil from getting. into floor dra1ns '* 2) using
.. 50 cubic foot waste liner. tanks and availab_le pumps,. the majority of the o~i was collected and is being stored on site awaiting shipment for re-processing, and 3) expedite getting Hydrogen *off.themachin~ and re..;
J>laccd ~ith carbon ~ioxide.~. These actions were extremely ef fect~.ve in minimizing the ahi.oui1t of oil which reached the floor drains **.
- The maximum amount of oil whi~h reached* the Turb.ine Sump Separator* Tank
- (T 41) was about 80-gallon~.
Follow-up actions taken after the incident were as follows:
- 1)
On Thursday, July 3, 1980, Stoddard & Sons of Hayland.was called in to remove the accumulated oi.l in tl:le T.urbinc Sump_ Separator Tank (T41) *
- 2) *** The.T 41 discharge sampling.proera:m was increased to a daily sam!Jle.
to.accurately monitor.~hc*discharge.
- 3)
A passive* oil* remov~*l filter was placed in the s'torm dniln into which
