MEMORANDUM FOR:

E. L. Jordah, Executive Officer for Operational

Support, IE:HQ

FROM:

R. H. Engelken, Director, Region V

SUBJECT:

FOLLOWUP INVESTIGATION OF A RANCHO SEC0 ALLEGATION

(1) Memorandum, Jordan to Engelken, " Request for

Investigation into Rancho Seco Allegations,"

dated May 3, 1978

(2) Memorandum, Engelken to Jordan, " Investigation

into Rancho Seco Allegations," dated May 26, 1978

Enclosed is a followup investigation report on the allegation identified by

Enclosure 1 of reference (1).

This additional investigation work was conducted to examine the allegation

in the light of a specific set of calculations identified by the alleger

which you telefaxed to W. G. Albert of Region V on June 7,1978, after

the initial investigation had been completed, refennce (2).

Our findings show that a decimal point error in a supplemental calculation

does exist but that the error is of no significance.

No further investigation effort was applied to Allegation V since the

information supplied by the alleger regarding the identity of two persons

formerly employed by the Bechtel organization does not appear relevant in

the light of our original investigation findings.

Per your telephone conversations with W. G. Albert, we intend to make

normal distribution of these reports. The one concern of the inspector

with regard to Bechtel's design calculation checking procedure will be

referred to Region IV-VIB for whatever followup they deem advisable with

regard to current Bechtei practices.
