    specifications and drawings to assure that specific technical
    requirements and commitments contained in the Construction
    Authorization Request (CAR) and the Safety Evaluation Report (SER)
    have been translated into vendor purchase documents. Verify the
    following:

    1.  Fire protection equipment associated with the fire-suppression
        systems specified in the CAR (as noted below) have been
        identified and specified in procurement documents:

```{=html}
<!-- -->
```

        requirements been identified or specified in procurement
        documents.

    5.  Critical dimensions are specified. (Size and location of water
        supplies, size and location of all piping, and the depth to
        which they are to be buried, etc.)

    6.  Fire hydrants comply with NFPA or AWWA criteria.

```{=html}
<!-- -->
```
b.  [Receipt Inspection]{.underline}. Verify that receiving-inspection
    instructions require: (a) inspections for damage; (b) conformance to
    purchase specifications (including any special requirements); (c)
    proper identification and tagging; and (d) receipt of proper
    supplier/vendor documentation.

c.  [Storage]{.underline}. Verify that site storage procedures provide
    for proper identification, handling, cleanliness preservation,
    protection from adverse weather, and other physical damage and QC.

d.  [Installation]{.underline}. Verify that the fire suppression
    systems, as specified in Chapter 7 of the CAR have been properly
    installed and that installation work procedures provide adequate
    instructions for the following (if applicable):

    1.  Installation work is to be done by fully experienced responsible
        persons.

    2.  There are procedural controls of rigging and handling
        activities, to prevent damage to pipes, fittings, valves, and
        other equipment.

    3.  Proper locations of valves, hydrants, mains, etc., are clearly
        identified.

    4.  Fire-pump installation complies with NFPA‑20. Separation and
        protection are in accordance with CAR commitments and Regulatory
        Guide 3.16.

    5.  Dimensional checks are specified for levelness, alignment,
        clearances, etc.

    6.  Proper restraints are provided for all tees, plugs, caps, bends,
        and hydrant branches.

    7.  Installation of hydrants is in compliance with NFPA 24.

    8.  Proper backfill methods are specified.

    9.  Water-tank installation is in accordance with NFPA 22 standards.

    10. Proper flushing and hydrostatic testing of the fire-loop water
        piping are specified.

02.03 [Observation of Work and Work Activities]{.underline}.

a.  Visually examine pipe, fittings, valves, and hydrants before \--
    installation. (Sample sizes: at least two lengths of pipe and one
    unit of each type component.) Plain ends shall be inspected with
    special attention, since these ends are most susceptible to damage.
    Verify that commitments in the CAR are being met in the following
    areas:

    1.  Cleanliness;

    2.  Configuration of loop and appurtenances, relative to drawings;

    3.  Obvious defects, such as cracks and dents, are identified and
        evaluated for suitability for use; and

    4.  There are provisions for proper identification of components.

b.  Observe work activities or completed work during the installation of
    the fire loop. (Sample sizes: observe at least 25 percent of
    installation work and visually examine at least 50 percent of the
    completed work before backfill.) Verify the following items:

    1.  Components are installed with proper location and orientation.

    2.  All specified anchors are in proper places.

    3.  No apparent damage was done to fire-loop components during
        installation.

    4.  Ongoing work is being performed in accordance with approved
        procedures.

    5.  There is adequate QC inspection coverage.

c.  If possible, observe portions of construction-completion testing
    (hydrostatic testing and fire-pump performance testing). If testing
    cannot be observed, examine records of completed tests.

02.04 [Review of Records]{.underline}. Verify that the following QA
records indicate that applicable commitments have been met:

a.  Receiving inspection records. (Sample size: at least two);

b.  Shop fabrication records. (Sample size: at least two, if
    applicable);

c.  Installation records. (Sample size one each, if applicable);

    1.  Leveling, alignment, clearances;

    2.  Anchoring installation;

    3.  Backfill and soil composition;

    4.  Cleanliness;

    5.  Flushing;

    6.  Hydrostatic test; and

    7.  Fire pump full load operational and automatic starting tests.

d.  Nonconformance Reports, if any; and

e.  QA Audits.

88142‑03 INSPECTION GUIDANCE

03.01 [Definition]{.underline}. A AFire Loop@ is a main water-piping
loop for fire protection, usually feeding hydrants, standpipes, and
other fire-protection systems and components. Fire loops are provided to
permit feeding hydrants and other components and systems, from at least
two directions, for redundancy.

03.02 Applicable portions of the CAR and the Office of Nuclear Material
Safety and Safeguards SER should be reviewed to determine licensee
commitments relative to construction and inspection requirements, before
review in this area. Inspectors should determine which versions of the
industry codes and standards the licensee has committed to, in the CAR
or other docketed correspondence, to follow. They should obtain copies
of those documents and become familiar with those industry codes and
standards during inspection preparation. Inspectors should select a
sample size of sufficient quantity of items (a) to (d) to ensure that
the licensee=s procedures incorporate the appropriate commitments.

03.03 Inspectors should interact with the licensee to enable them to
learn his construction schedule, so as to be on the location when work
is in progress. These observations are best performed by observing
portions of work over a number of days. It is desirable to examine as
much completed work as finished, before it is covered by backfill.
Observation of the final construction testing (hydrostatic testing and
fire-pump-performance testing) is important because it is the final
verification that work was done correctly.

03.04 Inspectors should try to select record samples, for review, from
work that U.S. Nuclear Regulatory Commission personnel did not observe,
to help confirm that all work was done correctly.

88142-04 RESOURCE ESTIMATES

This IP is expected to take, on the average, 60 hours for review of
licensee/contractor activities. It should be conducted once, during
construction, over a 3 month period, as needed, to observe licensee and
contractor personnel competency.
