KDiORANDUM FOR: Region III Files. LaSalle TID'D:
P.obert F. Warnick, Director. Enforcement and Investigation Staff FROM:
C. A. Phillip, Investigator
SUBJECT:
TELEPHONE CO TIACT FROM MRS. JUDITH COODIE, ATIORNET, ILLINOIS ATIORNEY GENERAL'S OFFICE On February 22, 1982 I was informed that Mrs. Judith Coodie, an attorney.
in the Illinois Attorney Cencra,l's office (3,12-793-2491), had called concerning allegations made by via TV Channel 5 reporter Doug Longenie.
Information regarding these" allegations is contained in two nemoranda to Region III Files, one prepared by R. F. Warnick dated January 28, 1982, and the other prepared by J. E. Foster dated February 10, 1982.
Before speaking with Mrs. Goodie I attempted to obtain additional infor-t=ation regarding the allegations and any action we had taken or p1mnned to take.
The follwing information was obtained, prinarily through discussions with Roger Walker, regarding the items listed in the above menoranda.
1.
Conduit grounding is en industrial safety not a nuc1 car safety concern nna therefore uced not be pursued by NRC.
2.
Since it is not known whether Unit 2 vill be built, the NRC cannot force the licensee to take action to install a Unit 2 sensor.
3.
The absence of the heating pads would become apparent during pre-op testing.
This is a radiation safety concern.
In all likelihood tbc licensee has a ucans of tracking t' tis inatter to assure that the pads are replaced. We could with little effort confirm this.
4.
This natter is not of concern to NRC since this structure is not considered safety related, i.e. subject to seismic considerations.
5.
No additional infor: nation obtained.
6.
No additional information el led.

- Region III Files - LaSalle February 26, 1982 During a telephone conversation with Goodie on February 23, 1982, I discussed the above with her and indicated we were evaluating the a11cgations to decide what action we would take.
She indicated she would call Foster or me on March 1 or 2 to find out what we planned to do.
Goodie indicated she had talked with and asked whether he had made en allegation during our contacts with him regarding the drilling into rebar which he said had occurred during the early stages of construction.
I indicated that I was unaware of that allegation but that it would be of interest to us.
Following my conversation with Mrs. Goodie I was advised by Walker that the LaSalle Resident Inspector had determined tha,t the heating pad removal was documented on Pre-operational Deficiency No. 402 and they were required to be replaced prior to fuel load.
Regarding Items 5 and 6, Ron Gardner advised that we do n'ot inspect security equipment wiring.
I believe it is NRC's poi $ tion that security equipment must function as required by the licynsee's security plan commitments and if they fail compensatory mea 7ures must be taken until they are repaired and operational.
'lba the basis of the above it appears that there is no need to further pursue the matters has brought to our attention.
This should be conveyed to him and at the same time we should attempt to determine whether he has information regarding the drilling into rebar that warrants further action.

March 30, 1982 MEMORANDUM FOR:
R. C. DeYoung, Director, Office of Inspection and Enforcement FROM:
James G. Keppler, Regional Administrator, Region III
SUBJECT:
LA SALLE COUNTY NUCLEAR STATION - PETITION FROM ILLINOIS ATTORNEY GENERAL As you know, on March 24, 1982, the Illinois Attorney General petitioned the NRC to suspend licensing proceedings at La Salle pending investigation of recent-allegations and to institute a Show.Cause Hearing with Illinois as a party to the Hearing. The allegations deal with the overall adequacy of safety related structures as a result of widespread rebar cutting and specific structural deficiencies in the roof of the off-gas building._
A conference call was held on March 29 involving Messrs. Denton,. Case, Stello, DeYoung and Keppler to discuss the handling of these investigations.
We agreed that, because-the petition expresses concern that the off-gas building deficiencies had been verbally communicated earlier to NRC and that the NRC had concluded an investigation of these alleged deficiencies was not warranted, it would be prudent to have an independent review of this allegation by IE (since IE was not involved in the consideration not to investigate). This review should address both the technical adequacy of the off-gas building concerns as well as the NRC's handling of the earlier notification in this regard. With respect to the concerns associated with cutting through rebar this matter will be reviewed by Region III with technical assistance from NRR.
I realize your staf f is already depleted as a result of other investigation -
assistance you are giving us, and your willingness -to assist in this effort-is genuinely appreciated.

t OFF-Gt.5 BUILDING R03F REPORT f
- 1 PURPOSE i
The purpose of the report is to state inforr.ation regarding,the second allegation (Page 6. Request to institute a Sha.: Cause Proceeding and for other Relief - Tymne Fahner, Attorney General of the State of Illinois) o'n the Off-Gas Building roof.
The evidence shows that the allegation is false.
l BACKGROUND The concrete enclosure above grade as part of the Off-Gas Building is a non-safety related structure which houses Off-Gas Building HVAC Air Handling Units, HVAC Mater Cooled Condensing Units, HVAC Exhaust Filter Units. HVAC Control Panels and associated ractor control centers and switchgear.
The specification concrete compressive strength is 4030 psi at 93 days. While detailed quality assurance require ents were not required due to the building being non-safety related, they were applied as part of the overall Co : onwealth Edison / Walsh Construction Company quality effort.
FINDINGS The Off-Cas Building enclosure concrete (walls and roof) was poured on November 7,1975. Walsh Construction Corp 5ny(WCC) Q.C. Tom QCP-9A(Pour Checkout Card) was signed by the appropriate construction and Q.C. personnel and countersigned by a Comorwealth Edison Company Field Engineer.
Additionally, WCC Q.C. Forms QCP-6A(Reinforcing Steel Placenent Audit) and QCP-93(Concrete Placement Control Audit Form) were utilized and signed by MCC Q.C. personnel.
Concrete testing during the pour by A & H Engineering Corparation showed the concrete was' within specification requirements for slunp air content and placing temperature. The concrete ret compressive strength requirecents, the lowest cylinder break was 4670 psi at 90 days.
On September 25, 1979, Coron>:ealth Edison Company 0;ality Assurance l
pointed out sor,e surface cracking in the bottorr. of the Off-Gas Building roof.
i The area had a high density of concrete expansion anchors. An inspection performed by WCC Q. A. Supervisor, WCC General Superintendant and CECO Structural Engineer found the cracking to be surface in nature and no further action required.
A temporary construction power center transforner and switchgear were set cn the roof in 1976.
The unit weighed approxicately 6703 pounds.
The unit was set over a concrete beam in the longitudual direction and one end rested on the east concrete wall. A check was made to insure the roof would take the unit leading prior to installation. The unit was recoved in late 1981 as it was no l
lenger required.
