ERRATUM TO SAN IMIS OBISPO MOTHERS FOR PEACE'S MOTION TO REOPEN THE RECORD Intervenors, the San Luis Obispo Mothers for Peace (dSLOMFP") hereby corrects the following error in its Renewed Motion to Reopen the Record Regarding Pacific Gas and Electric Company's Application for a License Amendment to Extend the Term of the operating License for the Diablo Canyon Nuclear Power Plant (August 8, 1994):
On page 14, delete question marks after " computer code."
A corrected copy of page 14 is attached.
Respectfully submitted, Diane Curran Harmon, Curran, Gallagher &
Spielberg 6935 Laurol Avenue, Suite 204 Takoma Park, MD 20912 (301) 270-5518 August 12, 1994 PDR ADOCK 05000275 93 9408230176 940812 C

- 14 correct."
Id., Details at 6, emphas!.s added.
However, he "noted that the calculations did not demonstrate that any significant margin existed in the 140 inch limit."
Id.
According to the Inspection Report, PG&E plans to " reassess" the 140 inch limit in the 1994 refueling outages.
Id.
Thus, it appears that even if the 140 inch limit is adequate, it is only harely adequate, providing no margin of safety to accomodate the potential uncertainties in macrofouling and heat exchanger capacity.
j Clearly, this would be incompatible with PG&E's commitment, in response to Generic Letter 89-13, to protect the operability of I
the ASW system with adequate design margins.
2.
PGEE Misrepresented Results of Heat Exchanger Test Inspection Report 93-36 found that PG&E had not reported
'I accurately when it stated in DCL-91-286 that its computer model
" predicted that the heat exchangers would remove the design basis heat load at design conditions."
Id., Details at 5.
PG&E later responded that the test failure was due to a combination of (a) an abnormal degree of fouling in the heat exchanger, and (b) the nature of the computer code used for the test.
Inspection Report 94-08, Details at 4.
According to PG&E, if PG&E had used a dif-ferent, more commonly used, computer code, the test results would have been 101 percent of the design basis requirements.
Id.
Inspection Report 94-08 and the NOV do not specifically address the adequacy of PG&E's analysis of the computer code.
How-ever, Inspection Report 94-08 found that there was an " apparent violation" in that PG&E had failed to provide " complete and
