• ATTACHMENT 1 Relief Request RR-A7 COMPONENT DESCRIPTION Insulated Pressure Retaining Bolted Connections ASME CODE CLASS ASME Section XI Class 1 ASME EXAMINATION REQUIREMENTS In accordance with ASME Section XI, 1986 Edition, Subsection IAW 5242(a); for sy~tems borated for the purpose of controlling reactivity, insulation shall be removed from pressure retaining bolted connections for visual examinations VT-2.

BASIS FOR RELIEF It is the position of PSE&G that it is impractical to conduct VT-2 examinations on Class 1 bolted connections with insulation removed and the system at operating pressure and temperature because:

In accordance with Salem Unit 2 Technical Specifications, 3.4.10.1 does not allow pressurization of Reactor Coolant System to nominal operating pressure without heatup.

Re-installation of insulation requires exposing personnel to the safety hazard of elevated temperature (550°F) and pressure (2235 psig), which includes a heat stress environment.

The activities will be conducted at the end of the outage and have the effect of extending the outage by a minimum of two days.

Boric acid leakage, leaves boric acid crystal residue when it evaporates, therefore, it is not necessary to examine for boric acid leakage in conjunction with a pressure test.

ALTERNATE EXAMINATIONS During refueling, outages, when in cold shutdown, conduct a visual examination of bolted connections for evidence of boric acid residue with insulation removed. Corrective action will be in accordance with ASME Section XI.
