" Spacing of Reinforcing Steel" -

Paragraph No. 5.b.

3.

Licensee Action on Previous Inspection Findings (0 pen) Infraction (389/80-13-01) Improper Storage. This item concerns the licensee's improper storage of six ASME Class 1, 2 and 3 va;ves.

During the week of April 2S, 1981, the inspectors examined the valve storage areas which had been improved to comply witn regulatory requirements.

The inspection showed several examples which indicated that the improvement program was not yet fully implemented.

In that the licensee's commitment was in full compliance by May 1,1981, this item will remain open pending review af ter that date.

4.

Unresolved Items

-

<

Unresolved items are matters about which more information is required to determine whether tney are acceptable or may involve violation or deviation.

New unresolved items identified during this inspection are discussed in paragraph 5.b.

5.

Independent Inspection Effort a.

Construction Activities The inspectors condJcted a general inspection of the reactor building, auxiliary building and stainless steel pipe faorication shop to observe construction progress and construction activities such as welding, welding filler material control, material controls, and housekeeping and storage.

Reinforcing Steel With regard to the above general inspection on April 29, 1981, the inspectors accompanied by a representative of the licensee roted several examples of groups of three to five re1nforcing bars with the clear distance between bars less than one inch. Each group of bars was in a single layer. The above bars were extending out of the completed concrete containment cylinder wall at penetration 43 and at the equip-ment hatch. The above appears to be in conflict with the requirements of ACI-318-1971, paragraphs 7.4.1 and 7.4.5.

This will be examined in a subsequent inspection and will be identified as unresolved item 389/81-05-04: " Spacing of fleinforcing Steel".

Within the areas inspected, no violations or deviations were noted.

6.

Reactor Vessel Internals The inspectors reviewed procedures, reviewed records, and observeu wu*k activities as described below relative to the reactor vessel internals tc determine whether regulatory requirements are being met. The reactor vessel internals consisting of the upper guide structure (UGS) assembly, the core support barrel (CSB) assembly, the core shroud and lower support (CS-CS)

assembly and miscellaneous equipment are being installed by Combustion Engineering (CE) using FP&L procedures as listed below.

Review of Quality Records The inspectors reviewed the 1980 and 1981 storage and protection inspection records consisting of Form SQP-23.1.

The records were reviewed to determine whether installed vessel protection records anfirmed that access control, cleanliness and protection met procedure equirements. The records were compared with the existing condition of the vessel as observed in paragraph a. above.

Within the areas inspected, no violations or deviations were identified.

9.

Safety-Related Components The inspectors reviewed records and observed work activities as described below relative to safety-related components to determine whether regulatory requirements are being met.

FP&L Procedures SQP-47, Revision 3,

" Pipe Erection"; SQP-23, Revision 0,

" Preventative Maintenance"; and SQP-3, Revision 2,

" Material Control" govern the records and work activities examined.

a.

Observation of Work and Work Activities The inspectors observed installed gas decay tanks 2A, 28 and 2C; gas surge tank 2A; waste gas compressor 2A; and charging pumps 2A, 28 and 2C. The equipment was inspected to insure that procedures for storage, cleanliness, preservation and protection were being met. On April 29, 1981, during inspection of the above components, the inspectors found the following problems:

(1) A 1" nozzle on the side of gas surge tank 2A and a flanged pipe connection at the waste gas compressor 2A were open.

Paragraph 3.1.2 of SQP-47 reo' ires that open pipe, fittings, valves and

.

$

equipment shall be capped or covered when no work or inspection activity is in progress. Upon being informed, the licensee took immediate action to cover the openings.

(2) The electric motor for the waste gas compressor 2A was not being heated. SQP-23 and Form SQP-23.1 for the compressor requires that the motor be heated.

It was noted that the compressor had been worked on, but no work was in process during the shift (night) of the inspection or on the next day shift. Upcr. being informed, the licensee took immediate action to place heat on the motor.

The above problems indicate inadequate measures to control preservation of safety-related materials and equipment and are examples of violation 389/81-05-01 discussed further in paragraph 10.a.

Handling Piping, Various SQP 3-R2 SQP 6-R1 SQP 28-R0 SQP 47-R3 With regard to the above inspection in the area of protection, the inspectors accompanied by a representative of the licensee on April 30, 1981, noted approximately 15 examples of scaffolding supported by, or rigging from installed safety-related piping. The licensee stated that they had no documented procedures controlling the above practices.

Therefore, the licensee had not established adequate measures to protect stored equipment and materials.

The above combined with the axamples discussed in paragraph 9.a.

indicates that the licensee has not established adequate measures to control storage and preservation of equipment and materials. Failure

.

.

.

.

.

.

.

.

.

.

to establish adequate measures to control storage and preservation of materials and equipment in accordance with work and inspection instruc-tions to prevent damage is in violation of 10 CFR 50, Appendix B, Criterion XIII. This violation will be identified as 389/81-05-01:

" Inadequate Measures to Control Preservation of Safety-Related Materials and Equipment",

b.

The inspectors observed in process welding activities of safety-related piping field welds as described below to determine whether applicable code and procedure requirements were being met.

(1) Welding The below listed welds were examined in process to determine work conducted in e r:ordance with traveler; welder identification and location; wt ig procedure; WPS assignment; welding technique and sequence; materials identity; weld geometry; fit-up; temporary attachments; gas purging; preheat; electrical -kr;teteristics; shielding gas; welding equipment condition; interpass temperature; interpass cleaning; process control systems; identity of welders; qualification of inspection personnel; and weld history records.

(2) Welder Qualifications The inspectors reviewed the FP&L program for qualification of welders and weldirg operators for compliance with QA procedures and ASME Code requirements.

.

The following welder qualification status records and " Records of Performance Qualification Test" were reviewed relative to the weld joints listed in paragraph 10.b.(1),11.b.(1) and 11.b.(4)(a).

Welder Symbol Application PYP Safety-Related Piping PWP Safety-Reisted Piping PYI Reactor Coolant Pressure Boundary Piping PVP Reactor Coolant Pressurg Boundary Piping BAF Control Eleme,t Dirve Mechanism With regard to the above inspection, the inspectors, on April 29, 1981, noted that several welders took combination process welder qualification tests in accordance with Welding Procedure Specifi-cation Nos. 24, 39 and 50, on an 0.812" x 6" diameter grooved pipe test assembly. The tests consisted of 1/8-inch thick gas tungsten arc weld (GTAW) metal deposit followed by an 11/16-inch thick shielded metal arc weld (SMAW) metal deposit. The Welder Qualifi-cation Records fer the above qualification test states the welders are qualified for welding pipe butt joints from 3/16-inch to unlimited wall thickness.

.

The preceding is contrary to ASME Interpretation IX-78-92 dated September 25, 1978 in that the above test conditions would only qualify the testad welder for a maximum thickness of 1-5/8-inch.

-

<

Therefore the licensee has been granting welders unlimited thick-ness qualifications when the welders are actually only qtalified to 1-;/8-inch thickness maximum.

The above condition indicates inadequate measures for the control of special processes and is an example of violation 389/81-05-02 as discussed further in paragraph 11.b.(4)(a).

(2) Welder Qualification

Welder qualification is discussed in paragraph 10.b.(2).

(3) Welding Material Control Welding material control is discussed in paragraph 10.b.(3).

(4) Special Welding Activities The inspectors examined special welding activities as described below to determine whether applicable code and procedura.1 require-e ments were being met.

(a) Seal Welding The below listed weld was examined in process to determine:

whether work was conducted in accordance with travelers; welder identification and location; welding procedcre; WPS assignment; welding technique and ' sequence; ;naterial s identity; weld geometry; fit-up, temporary attachments; gas purging; preheat; electrical characteristics; shielding gas;-

welding equipment condition; interpass temperature; interpass cleaning; process control systems;. identity of welders; and weld history records.

4 With regard to the above inspection, the inspectors accom-panied by a representative of the' licensee, on April 29,

~

1981, noted the following examples of welders failing to follow welding procedure parameters:

Back purge was _16 CFH. WPS-75 RO requires back purge to j

be 3 to 5 CFH.

The tungsten electrode extention beyond the gas cup was

!

1/4-inch. WPS-75 R0 requires electrode extention to be

'

5/8-inch.

.

The above combined with the example as discussed. in paragraphs 7.e,10.b(1),10.b(2) and 11.b.(1) indicate that the licensee does

.

not have adequate taasures for the control of special processes.

]

Failure to establish adequate measures to control special pro-l cesses including welding is in violation of 10 CFR 50, Appendix B, Criterion IX. This violation will be identified as 389/81-05-02:

<

" Inadequate Measures to Control Welding and Welder Qualification".

(5) Welding Procedure Specifications Welding procedure soecifications are discussed in paragraph 10.b.(4).

Within the areas examined, no violations or deviations were identified except as described in paragraph Nos.11.b.(1) and 11.b.(4)(a).
