c.
The inspector reviewed audits performed by a PTL auditor and CECO Quality Assurance (QA) en PTL activities.
d.
The inspector aleo reviewed PTL QA Manual QA-M-1, Rev. 3, 4/6/77, the prs _ dure for qualification and certification of PTL NDE technicians No. QC-PQ-1-NDE, Rev. 3, 9/8/77 and the following PTL personnel certifications.

The inspec*or made a tour of the PTL f acilities escorted by the CECO QA L.ructural Coordinator and the PTL Site Manager.
The following are the inspector's findings.
(1) Radiographv (RT)

- PTL does not have a CO 60 source or a x-ray machine onsite.
- The Lab has four IR 192 sources stored in a locked concrete block room.
- PTL hauls the sources from place to place onsite in a pick-up using correct radioactive signs.
- A hand film processing tank is used to process f'lm.
- Survey meters are calibrated every 90 days.
- Docket dosimeters are read and recorded every day when performing RT.
- Film badges are processed and recorded every month.
- Acceptable color rope and signs were available for securing areas when radiography is being performed.

.
- Film cassettes were in acceptable condition.
- Lead screens are checked every week and replaced if necessary.
- Fluorescent screens are not used nor are there any onsite.
- The film are stored in the dark room prior to exposure.
- The exposed film is stored in a brick, air conditioned, heated and humidity controlled vault.
- PTL uses lead numbers for the number belt and a flasher for the identification.
- The lab uses a X-2ite densitometer in acceptable condition.
- PTL uses a film density step wedge traceable to the Bureau of Standards for the calibration of the densitometer.
- ASTM penetrameters are the only penetrameters used onsite.
They were in acceptable condition and had certifications.
- PTL had various thicknesses of shims to be used under the penecrameters.
- The inspector reviewed Chicago Bridge and Iron containment liner plate welds 46-93 radiographed on 9/13/76.
- The inspector reviewed the following procedures and field and shop radiographs of welds in various systems.
RT Procedures Radiographic Examination Procedure No. QC-RT-1, Rev. 4, 9/E/77.

Residual Heat Removal (PC) Primary Containment and Reactor Vessel Isolation (SX)
Essential Service Water (WO)
Chilled Water in reviewing the radiographs of the shop welds, the inspector found that all the radiographs had the lead letter "F" placed on the penetrameters and not placed adjacent to the penetrameters as required by ASME Section V, 1974 Edition with 1975 Addenda, Article 2.
The licensee representative acknowledged the problem and placed a telephone call to SFWC.
SFWC informed CECO that approximately three years ago, a code inquiry was made to the American Society of Mechanical Engineers (ASME)
Committee on this subject and a reply was received stating that the lead letter "F" on the penetrameter was acceptable. Until a copy of this letter is reviewed by an NRC inspector, this is an unresolved item.
Radio-graphs
,# these shop welds met all other requirements.
(454/79-07-01; 455/79-07-01)
(2) Magnetic Particle (MT)
- The inspector observed magnetic particle examina-tion, yoke method, being performed on pipe welds, CC-20-1.
The inspector also observed the yoke, (Parker Probe Model 200) picking up a 10 lb. weight using alternating current -
a pole spacing of 3-6 inches.
The setting of t...
ske was then turned to direct current and a 50 lb. weight was picked up with a pole spacing 3-6 inches.
This was performed in accordance with AFME Section V, 1974 Edition with Summer 1975 Addenda.

- Ultrasonic Inspection Procedure No. QC-UT-1, Rev.
1, 9/8/77 and Ultrasonic Inspection Welded Structural Steel Procedure No. QC-UT-2, Rev. 1, 1/24/77 were reviewed and found to be acceptable.
(5)
Eddy Current (ET) Visual (VT), Leak Testing (LT)
To date PTL has not performed ET, VT or LT onsite.
No items of noncompliance or deviations were identified.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of noncompliance o-deviations.
An unresolved item disclosed during the inspection is discussed in Paragraph 1.f. (1).
