s NOV 2 01987 Docket No.: 50-312 Mr. G. Carl Andognini
' Chief Executive Office, Nuclear Rancho Seco Nuclear Generating Station 14440 Twin Cities Road Herald, California 95638-9799 i
Dear Mr. Andognini:
I
SUBJECT:
TI"ELY RESOLUTION OF CURRENT INSPECTION ISSUES 1
This letter is to confirm our understanding of SMUD's plans and schedule to resolve selected issues in the areas identified below.
Region V believes that these particular issues must be satisfactorily resolved by SMUD.in an expeditious manner to allow the NRC adequate time to review your resolution-prior to your projected plant restart date of January 15, 1988.
Significant delays in resolution may impact your projected plant restart date.
The issues are:
1 1.-
POST ACCIDENT SAMPLING SYSTEM:
It is our understanding that performance problems experienced during testing of the PASS system are not expected to be resolved until January 7,1988,.one week prior to your current restart date. This raises serious concern whether we can perform our inspection to confirm PASS operability without causing a schedular impact.
2.
PROCUREMENT:
Region V inspections, as well as the second ASTRP inspection in October, 1987, identified potential weaknesses in warehouse segregation of safety related material. The NRC needs to better understand your perspective as to the extent quality assurance requirements for procurement, storage, and handling of safety related material were met at Rancho Seco from initial construction to the present. The potential for non-safety components to have been inadvertently used in safety-related applications in the plant is of primary concern.
1 We understand that SMUD will be prepared to discuss this issue and any appropriate corrective actions planned or already taken, in detail, at a j
meeting in Region Y currently scheduled on November 24 at 9:30 a.m..
3.
EMERGENCY OPERATING PROCEDURES:
NRC Inspection 87-34 determined that SMUD had not justified deviations from the latest generic technical basis document used for the emergency operating procedures, and that the NRC had not been kept informed of SMUD's change in technical bases from one confirmed by NRC Order to one unapproved by the NRC.

Mr. G. Carl Andognini -
We understand that SMUD will provide justification for all deviations
-from the generic technical basis for the emergency operating procedures (less their associated transient cooldown procedures) by November 30,
.1987.
.It is also our understanding that SMUD intends on providing justification for the transient cooldown procedure deviations promptly, but not necessarily prior to restart. The NRC is still reviewing the acceptability of delaying this action until after restart at Rancho Seco, as well as the acceptability of the new technical basis.
4.
.' TEST PROCEDURE AVAILABILITY: The' NRC expects that a reasonable period of.
time be available for our review of. major test procedures prior to performance. The procedures requested include: the loss of offsite power test; hot functional testing; all integrated ICS and EFIC testing; initial criticality; and power ascension testing, including reactor. trip testing. Typically,.for a new construction facility, test procedures are expected to be available for our review at' least 30 days prior to use.
SMUD provided only several days for NRC review of the loss of offsite power test prior to its start. As a result,.the NRC is currently commenting on this test while it is being performed.
It is possibir %
the NRC may find that certain additional loss of offsite power tr.u ng may need to be performed after the procedure review is completed.
We understand that in the future SMUD intends to provide'a copy of the
. approved test procedures for the remaining tests identified above at.
least five working days prior to the scheduled start of the test to Region V and NRR. This period is understood to be the time that the test procedure is in the possession of NRR and Region V.
(The NRC recognizes that additional. minor editorial or technical changes to the procedure may occur in thisiinterval.)
5.
RESTART SCOPE LIST CONCERNS: Region V recently reviewed a sample of the problems identified by SMUD on its Long Range Scope List. This review,-
documented in Inspection 87-30, concluded that SMUD had appropriately deferred these items until after restart. -Since that review, Region V has learned that about 300 additional items have been added to the list which we reviewed. This is of concern to the extent that some items may have been reclassified from'the Restart Scope List to the Long Range Scope List.
In addition, Region V intends to review the actions taken on the findings of the Expanded Augmented System Review and Test Program conducted by SMUD as a special category, in greater detail, in a future-inspection.
We understand that SMUD will provide Region V with updates of. the Restart Scope List and Long Range Scope List changes, including all additions and deletions, as substantive changes occur.
In addition, Region V requests that SMUD clearly identify the status of all EASTRP findings as soon as possible so that we may review this status prior to restart.

'l Mr. G. Carl Andognini It is my understanding that the SMUD commitments identified in this letter have been discussed and agreed upon in previous conversations and meeting between our respective staffs.
If you believe these commitments have been misstated, or you wish to modify any of them, please advise me or my staff promptly.
I am encouraged by SMUD's continued progress towards a safesrestart of Rancho
'Seco. As we have discussed, I believe that clear communication to assist in resolution of the remaining safety issues is essential to achieving that goal.
