Organization Changes (MP&L)
a.
i
Mr. J. E. Wimberly, MP&L Construction Supervisor, has lef t the
zmployment of MP&L to accept employment with Gulf States
j
Utilities at the River Bend project.
Mr. G. E. Osborne,
previous MP&L civil QA representative has replaced Mr. Wimberly.
b.
Contractor Changes
I
The contract with the heat and vent duct contractor, IRSAY,
Skokie, Illinois, has been cancelled. The contractor was
performing both safety and non-safety related work.
Records
from IRSAY were turned over to Bechtel QC records prior to
IRSAY leaving the site.
General Mechanical Contractors has
been contracted to complete the heat and vent duct work.
c.
General Site Inspection
The inspector walked through Unit I and 2 facilities observing
general storm damage to the main structures and support facilities.
Additionally the inspector observed concreting prepour and
placement activities relative to Unit 2 and walked through the
main warehouse.
Considerable discussion was held with MP&L
management relative to the project schedule.
5.
Partial Mid-
Term Construction Permit QA Inspection - Field Procurement
TUnits 1 and 2)
The inspector reviewed the on-site program for procurce nt of
structural support material.
Bechtel Specification Nos. 9645-C-
121.0, 9645-C-131.0, and 9645-C-151.0 are the specifications for
the furnishing of structural steel for category I structures;
miscellaneous and embedded steel and iron for Category I structures;

forms.
Bechtel QA Instruction No. 4.1-1 instructs the project QC
Group on how to review and approve the field material requisitions.
The Field Procurement Individiual Jobsite Instructions describe how
field procurement performs their functions. The procurement depart-
ment utilizes an approved venders list for selection of bidders.
The inspector selected purchase order Nos. 9645-F-25346 and 9645-F-
25714, for structural materials, to determine whether the QA canual
procedures were implemented, whether the specification requirements
were imposed, whether supplier documentation was required, whether
the supplier was prequalified, and that the field QC records contained
the required documents.
The material requisitions were in order
and properly reviewed and signed off; the purchase orders referenced
!
the applicable specification, materials, tests reports, part 21 and
documentation requirements; the field QC records contained the
Material Receiving Instruction and Inspection Record, Material
Receiving Report, Documentation Requirement Forms, Material Test
Reports and purchase orders,
f
No items of noncompliance or deviations were identified.

10 CFR 21 Inspection
The inspector selected Purchase Order Nos. 9645-M205.1, Rev. 21;
9645-M-257.0, Rev. 16; 9645-C-121.0, Rev. 35; 9645-M-062.0, Rev. 9;
9645-M-300.0, Rev. 21; F-25346; and F-25918 to verify that purchase
documents initiated at Gaithersburg and at the site were including
the Part 21 clause. The inspector confirmed that all purchase
orders did include the part 21 clause.
Additionally the inspector verified that three on site subcontractors
were complying with the posting requirements of Part 21.
During the period of the inspection the licensee discovered that
Bechtel subcontracting had failed to impose Part 21 requirements on
a subcontractor, General Mechanical Contractors (See Paragraph 4.b
above). This matter was quickly corrected by amending the contract
to impose Part 21 requirements.
No items of noncompliance or deviation were identified.

Licensee Identified Item
Small Fire - Reactor Vessel Pedestal Area (Unit 1)
!
On April 4, 1978 MP&L notified IE:II of the occurrence of a small
j
fire which had developed underneath Unit I reactor vessel. The
fire was determined to have been caused by an electrical short in
110 volt extension trouble light. The short ignited some plastic
a
covers and burlap which burned for less than two minutes. The fire
extinguished with a dry chemical type extinguisher.
The reactor
vessel bottom head was filled with black soot and powder from the
I
extinguisher was adhering to the inside of the vessel skirt and the
Leue; of the vessel.
Ash and powder fell to the control red drive
piping work platform and on the insert withdraw lines.
-
The inspector reviewed the Bechtel Safety Department Fire Report;
the Bechtel, Reactor Controls Incorporated; General Electric I&SE
nonconformate reports; and the General Electric hTD engineering
evaluation and cleanup instructions. MP&L and their contractors
have concluded that there was no damage to safety related equipment.
This matter is thoroughly documented in on-site records and appears
to have received adequa e attention.
IE:II has no further questions
regarding this matter.
10.
Management Interview
The inspector met with the licensee representatives (denoted in
paragraph 1) at the conclusion of the inspection on May 19, 1978.
The inspector summarized the scope of the inspection as follows:
Licensee action on previous inspection findings; independent inspec-
tion effort; mid-term QA; IE Bulletins; 10 CFR 21; and licensee
identified items.
No items of noncompliance were identified.

Unresolved Items
Unresolved items are matter about wh?ch more information is required
in order to ascertain whether they are acceptable items, items of
noncompliance, or deviations.
An unresolved item disclosed during
the inspection is discussed in Paragraph 4.
4.
Independent _ Inspection Effort
a.
Warehouse:
During a backshift inspection, the Bechtel receiving warehouse
on site vas inspected. As an added precaution, metal cabinets
!
housing c >ntainers of flammables have been moved outside the
l
warehouse.
This prevents the possibility of fires near stored
Class I materials and equipment caused by inadvertancies such
as piercing a cabinet with fork lift prongs.
b.
Concrete Placement:
i
The inspectors observed a night shift placement of a portion
of a 2,700 cubic yards section of the foundatica cat of the
Unit 2 auxiliary building under WP61R Q2 T-21-W-21093 using
CC2 mix.
For each 50 yards, sampling was done et the mixer
discharge site into the trucks. For each 500 cubic yards,
samples were taken at a pump line discharge.
In review of the concrete mixer report, test data and the QC-
2C Supplement Report for pump line discharge sample test data,
the inspector noted some apparent improbabilities.
The four
samples taken had a recorded slump of 2 1/2 inches although
the same mixes sampled at the mixer had variable slumps.
Also, the recorded air entrainment percentages recorded show a
reducing differential, or drop, in slump as the pipelines were
shortened, an actual rise for one case (4.5% at the mixer,
2.8% at the truck discharge and a rise to 3.7% at the end of
the pump line.) The inspector challenged these aberrations.
MP&L QA had Bechtel QA mnd QC engineers review the data and
confer with Pittsburg test laboratories.
PTL maintained that
the test data had been recorded correctly.
This indicated
that perhaps the instructions for recording slump measurements
at the pump line end may have been misunderstood by the technician
and the air entrainment measurement devices might be out of
(
calibration or the measuring technique not followed correctly

Procedures - Fire Prevention / Protection
The licensee's com=itments on facilities to be provided for fire
i
prevention, suppression and urotection were published in PSAR
section 3, Criterion 3 - Fi e Protection and section 9.5.1 Fire
Protec_ tion System. Additional criteria are set out in the construction
specifications and drawings.
Additional criteria and guidance are available in proposed Regulatory
Guide 1.120, Fire Protection Guidelines for Nuclear Power Flants
(out for comment until November 1978) and the NPPH, ANSI, ASTM,
IEEE, MAERP-NELPIA, and U.S. NRC regulatory guides and other Commission
documents listed in the Reference to R.G.
1.120.
The licensee is implementing, as the status of construction permits,
the requirements and guidance of the controlling criteria and
guidance through Bechtel WP&IR No. NSA 13-2-00000-Y01, Revision 3.1
dated July 7, 1977, " Procedure for Controlling and Extinguishing a
Fire on Grand Gulf Construction Site"; by supplemental field instructions,
written and verbal; by periodic scheduled training of fire brigade
personnel and by weekly inspections of fire extinguishers, hydrants,
loop line and installed sprinkler systems; housekeeping; and by a
fire permit system.
The inspector reviewed the WP&IR and the supplemental documents and
discussed them in detail with the Bechtel Project Safety Supervisor.
(
The installed permanent fire protection systems were inspected.
