The inspector observed the liquid penetrant testing of pipe weld
No. HBC-91-8/3 FW 10,11, and 12 for Unit No.1 and DCA-418-4W4 for
Unit No. 2.
He verified that the tests were perfomed in accordance with
ASME III Code and IPPT-340-39-02 procedure requirements. Weld HBC-91-8/3
FW 6,10, and DCA-418-4-W4 were rejected by the nondestructive testing
technician because of indications which required additional surface
treatment. No violations were identified.

Electrical Separation Criteria
The Bechtel Specification E-1412, " Wiring and Cable Notes and Details",
paragraph 6.3 " Engineered Safeguard and Reactor Protection System Equipment
Separation-Design Basis", allows separation distances less than those
required by IEEE-384. The specification states, in part, "When a 6"
separation cannot be achieved, a minimum 1" separation between safeguard
and non-safeguard is required or a flame retardant barrier shall be provided."
The L.imerick FSAR, paragraph 8.1.6.1.14 states that the plant design meets
IEEE-384 with qualified exceptions.
IEEE-384, paragraphs 4.5, 5.1.3, and
5.1.4 requires that separation of associated circuits (nonsafeguard) be
maintained at not less than 1" between enclosed raceways or between barriers
and enclosed raceways.
The licensee acknowledged that the current edition of the FSAR was not
consistent with the procedure. However, he noted that the FSAR is
currently being revised to include analyses to support his practices. This
item is unresolved pending revision of the FSAR (352/81-17-04).
7.
Licensing Meeting
The inspector attended the Atomic Safety and Licensing Board special
preheating conference on January 6, 7, and 8, 1982. The purpose of the
conference was to establish general rules of practice and receive clarifying
statements for selected contentions.
8.
Unresolved Items
Unresolved items are matters about which more information is needed to
determine if the item is acceptable, a violation, or a deviation. Unresolved
items are discussed in 2, 4, and 6.
9.
Exit Interview
Exit interviews were held on December 10 and 23,1981, with members of the
licensee's staff listed in paragraph 1.
The inspector discussed the scope
and findings of the inspection.
