inspector of civil/structural activities relating to construction of the new emergency diesel generator building (NEDG).
The inspection consisted of a review of construction specifications, of quality control requirements, observation of construction activities, verification of construction controls and a review of quality control records of completed work.
The review also included the licensee's quality assurance audits of the construction activities.
The inspection involved 19 inspector-hours on site and two inspector-hours of in-office review.

New Emer enc Diesel Generator Bui ldin -Site Activities 2. 1 Sco e of Ins ection The inspection was conducted to review with licensee and contractor personnel the status of ongoing activities in construction of the new emergency diesel generator building.
The inspector's review was concentrated on, but not limited to, the following quality related elements:
Adequacy of site preparation and excavation for the NEDG building foundation as required by Gibbs
& Hill (G8H)
specification No. C-1038.
Concrete construction specification of G&H No. C-1042, related drawings and referenced codes and standards.
Certification of the concrete batch plant and truck mixer Qualification of concrete aggregates, cement water, concrete additives and reinforcing steel.
Design of concrete mixes, their proof testing and uniformity testing of the truck mixers.
Certification of testing laboratory and test personnel qualifi-cations.
Implementing work and quality control inspection procedures by DCI.
Quality assurance plan of the licensee and his audits performed on DCI construction activities and controls.
The inspector observed construction activities during this in-spection to evaluate work performance and quality control of con-crete batching, mixing, delivery and placement of fill concrete above rock prior to construction of base mat for the NEDG build-ing.
Records of excavation, rock mapping, rock treatment and fill concrete placement.
2.2 Record Review of Site Pre aration - Rock Ma in and Rock Treatment Records of rock mapping by Dames
& Moore and treatment of the exposed vertical joint in foundation rock were reviewed.
The three step in-structions for grouting of the open joint in the sound rock with a non-shrink flowable grout mix were observed consistent with G&H speci-fications and instructions.
2.3 uglification of Concrete Materials - Batchin and Mixin E ui ment The inspector reviewed G&H specifications, control requirements and OCI implementing quality control procedures relating to the qualifi-cation of concrete materials, the new Erie-Strayer automatic batching plant and of concrete mixer trucks.
He also discussed these elements with DCI QC personnel and inspectors and reviewed the quality docu-mentation generated in this effort.
The inspector's scanning review of records found they technically fulfilled requirements of G&H specifications and referenced codes and standards.
2.4 Observation of Concrete Construction and Review of ualit Control Activities/Their Documentation The NEDG building site is underlaid by sound rock which is at Elev.
639 at the north half.
The rock dips sharply to Elev.
625 at the center then levels off to the south.
The site was prepared for excavation by installation of steel H soldier piles surrounding the
area.
As excavation was carried down to sound rock, timber sheeting was installed to prevent caving of the walls of the excavation below the original grade Elev.
675.
The design of the NEDG building base mat at Elev. 652'-6" thus requires fill concrete placement above the top of rock.
The construction observed during this inspection con-sisted of fill concrete placement in the south'alf from Elev.
640 to 645.
The inspector observed and evaluated the quality aspects of this safety related work activity in the following areas:
batch plant proportioning of concrete ingredients for 3,200 psi, class A concrete mix, number A6 truck mixing of the 10 cubic yard loads and delivery to the concrete pump construction joint treatment and removal of excess water concrete pump placement, consolidation and curing concrete testing and quality control verification of the above activities generation of control records The safety related records of previous fill concrete placements were reviewed.
The above activities and records were observed to fulfill requirements of the GKH specifications and DCI's gA program.
2.5 Review of Licensee Audits and Surveillance of DCI Construction Activities and ualit Control Documentation A review was performed of the licensee's quality assurance plan per-taining to the emergency diesel generator project.
The plan is iden-tified as PPAL Operational Policy Statement, Appendix OPS-1-H revision
¹ This document states that the new emergency diesel generator NDEG project involves the installation of a fifth EDG to be used as a
replacement and will have the capability of supplying the emergency loading for any one of the four existing diesel generators.
The plan provides a mechanism for addressing and controlling the coordination-of interdependent organizations, the establishment of controls to define the division of authority and responsibility for accomplishing their respective activities, and the required organizational interfaces.
This gA Plan applies to PP8 L and GEH for general consulting services.
It also applies to GEH in managing the performance of its quality related activities affecting DCI's scope of work for the construction of the NEDG building.
The inspector performed an overall review of the licensee'
audit/surveillance activities relating to DCI'
con-struction activities.
His review included the following:
PP&L site audit ¹C84-05 performed during May and June, 1984 re-lating to DCI's preconstruction control procedures for qualifi-cation of concrete ingredients, design of concrete mixes and certification of batch plant and'mixer trucks.
This audit utilized a check list of 16 characteristics relating to G&H'
concrete construction specification and referenced codes and standards.
PP&L letters to G&H and DCI on Audit ¹C 84-05 findings/correc-tive action for one item of noncompliance.
PP&L letter of July 6, 1984 to OCI on findings resulting from PPL surveillance of DCI's concrete testing laboratory activities in concrete materials qualification, design of mixes and testing; no items of noncompliance were noted.
PP&L Site audit ¹QSAR 84-062 dated August 2, 1984 pertaining to surveillance of site activities of batch plant and mixer truck certifications, and concrete mix uniformity testing of trucks.
This resulted in 18 findings transmitted to OCI August 2, 1984 and called for response within 30 days.
The results of the sur-veillancee concluded that DCI had performed certification testing satisfactorily.
However the 18 findings reflect discrepancies due to lack of documentation reviews and verification that in-spection records were complete.
The NRC inspector concluded from his review of the above records, discussions with licensee QA auditors and DCI's QC supervisor that DCI is lacking in site level QA management personnel to re-view and approve the completeness of QC inspection records sub-mitted by the QC supervisor.
The latter's duties were observed to be preempted by field activities.
As related to licensee QA surveillance report QSAR ¹84-062 findings on the programmatic deficiencies in DCI's inspection reports, additional QA office personnel are needed.
The present records management responsi-bility under the project engineer appears to be inadequate.
Pending DCI's response/corrective actions on licensee audit
¹84-062 this is identified as NRC unresolved item number 50-387/84-30-01, 50-388/84-36-01.
No violations were identified in the above areas, 2. 1 through 2'.
3.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable violations, or deviations'n unresolved item identified during this inspection is discussed in Paragraph.
Exit Interview The inspector met with licensee and contractor personnel (denoted in Paragraph 1) at the conclusion of the inspection on August 8, 1984 at the construction site.
