Fabrications of Safety-Related Piping Systems During the reporting period, the inspector observed work including a.
handling, protecting, inspection, and welding of-safety-related piping systems.
(1) Main Steam System 2AB-01-F008 2AB-01-F009 (2) Component Cooling Water System 2EG-07-FOP.2 For each of these welds one or more of the following fabrication activities was observed. Handling and protection of piping and partially completed welds was satisfactory. Purge gas was cor-rectly used. The weld area was free of any grease or particles.
The joint fit-up dimensions were within procedural requirements and the welders were certified os qualified for the procedure specified to be used for welding the pipe joint.
No items of noncompliance or deviations were observed.
4.
Containment Building Prestressing During the reporting period the inspector observed the following a.
work associated with prestressing.
- (1) The installation of button heads on tendon 25CB was observed.
The heads were checked for size, concentricity and the presence of unacceptable cracks and tears.
(2) The filling of tendon sheath V-82 with protective grease was observed. The temperature of the grease was satisfactory and inspection personnel were observing the operation as required by procedure.
No items of noncompliance or deviations were identified.
5.
Ccncrete Placement During the reporting period the inspector observed portions of a.
the following safety-related concrete placements: 2C261W21 Pressurizer Enclosure 2C261W23 Pressurizer Enclosure 2C261W20 Pressurizer Enclosure 2C661501 Fuel Building Roof i-3-

During the placement the following conditions were noted.
. (1) The forms were secure, leak tight, and had been wetted prior to the placement.
(2) The preplacement inspection had been completed and was in order.
(3) Quality Control inspectors were assigned to the placement crew in addition to those assigned to perform periodic concrete testing.
(4) Concrete testing was performed at the required frequencies.
(5) Adequate numbers of crews and personnel were assigned to make the placement.
(6) The placement was satisfactory.
. No items of noncompliance or deviations were identified.
6.
Drawing Control During the inspection period,12 drawings were checked in the Fuel Building to determine if drawings of the latest revision were being used in the construction effort. Drawings in the electrical area of work were checked.
It was found that all drawings were of the correct revision and change notices, when issued, were attached to the, drawing.
, No items of noncompliance or deviations were identified.
7.
Reactor Vessel Internals During the inspection period the inspector observed welding of locking devices on the reactor vessel lower internals. Weld No. FS-M-D5365-FW-2 was observed. The weld appeared satisfactory, had been welded by a qualified welder and inspected by a qualified inspector.
No items of noncompliance or deviations were identified.
8.
Construction Completion and Pre-Operational Testing During the reporting period the inspector reviewed the basis for, and control of, construction completion and pre-operational testing.
Union Electric's procedures.for performing testing and quality control work were also reviewed.
The review of PSAR, FSAR, Federal Regulations, Regulatory Guides and Union Electric procedures resulted in questions concerning the clear establishment of organizational responsibility for the quality control (inspection) of work performed in support of construction completion testing and pre-operational testing. Nuclear Construction Administrative Instructions describe the function as being beformed within the testing organization; whereas, the PSAR describes it as part of the Quality Assurance Organization respon-sibility.

. Quality Control inspections regarding the construction completion and pre-operational testing have not yet started.
Pending the receipt of clarifying information concerning the definition of responsibility for quality control and a listing of the quality control implementing procedures this is an unresolved ites.
(Item No. 50-483/81-09-01) Unresolved Items: Unresolved it' ems are matters about which more information is required in order to ascertain whether they are acceptable items or items of non-compliance or deviations. Unresolved items disclosed during this inspection ~~ are discussed in Paragraph 8.
' Other Activities The inspector participated in meetings and a tour of the plant as a result of site visit on 4-27-81 by D. C. Gupta of the Hydrologic and Geotechnical Engineering Branch of the 0ffice of Nuclear Reactor Regulations Exit Meetings The inspector met with Licensee representatives (denoted under Persons contacted) on April 24 and 30, 1981 and other occasions throughout the month. The inspector summarized the scope and findings of the inspections performed. The Licensee representatives acknowledged the findings reported in previous paragraphs.
