- This letter is in response to your November 9,1989 letter (copy attached) requesting enforcement discretion, and confirms the telephone cuniersation of
' November 10, 1989 between Mr. Jeffrey Smith and other members of'your staff and Mr. Thomas T. Martin and other members of my staff granting your request.
Thisl request was for'one-time enforcement discretion regarding containment.
integrity Fequirements due to the administrative inoperability of the emergency dieselfgenerators that occurred at 6145 p.m. on November 9, when the service
/ water pump. discharge strainers were determined analytically to be not qualified g
'to appropriate-seismic criteria, t.
P Specifically.for.the reasons described in your letter and discussed in that k
telephone conversation, this action grants relief from Millstone 2 Technical SpecificationL3.8.2.2, "A.C. Distribution - Shutdown" requirements to establish L
containment integrity per Technica1' Specification 1.8.2, regarding closure and L
! sealing-of'the containment equipment hatch within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> from the loss of diesel operability.
L
,In lieu of full closure of the hatch, you propose to implement procedures and
' administrative controls that you established in response to Generic Letter 88-17
'" Loss:of Decay Heat Removal" that would assure containment closure within 122 minutos.
It is our understanding that the electrical buses referenced in r
' Technical-Specification 3.8.2.2 will remain energized from sources of power i
t.
tother than a diesel generator and that diesel generator power will remain j
o Lavailable to the buses. This enforcement discretion specifically applies to the alternate method of containment closure and authorizes an extension of the time-the plant may continue with cold shutdown activities without full i
f Jcontainment closure while the diesels are administrative 1y inoperable, j
