with position stated in (new Subsection) II.2. Accident monitoring instrumentation should be appropriately qualified if it is not located in seismically qualified buildings and citing Subsection II.2 will provide appropriate assurance. 35. Editorial Changed "assure" to "ensure." 36. Integrated Impact No. 273 Added sentence to conform to NRC positions on limiting stresses in valve bodies and pump casings. (ABWR FSER Section 3.10) 37. Integrated Impact No. 263 Changed IEEE 344-1975 to ANSI/IEEE Std 344-1987 to conform to latest staff guidance contained in Regulatory Guide 1.100. 38. Editorial Defined "LOCA" as "loss-of-coolant accident." 39. Editorial Changed "assure" to "ensure." 40. Integrated Impact No. 263 The first sentence of the existing paragraph was made obsolete by the adoption of ANSI/IEEE Std 344-1987 by the NRC staff and the resulting revision of Regulatory Guide 1.100. The current version of Regulatory Guide 1.100 does not describe ANSI/IEEE Std 344-1987 as an "ancillary standard" to IEEE Std 323-1974 and therefore the statement required correction. The second sentence of the paragraph was modified because the reference to "plants whose construction permit SER is dated July 1, 1974, or later" is redundant. All plants that will be covered by this SRP revision are in this category. (Last paragraph of Section 4 of ANSI/IEEE Std 344-1987) 41. Integrated Impact No. 264 Added Subsection II.2. to ensure that instrumentation will be seismically qualified. The text was adapted from the 4th paragraph of the Introduction to Regulatory Guide 1.97 as well as the 4th paragraph of Item 1 of Table 1 of Regulatory Guide 1.97. 42. SRP-UDP update item Deleted existing Subsection II.2. There are only two plants whose CP applications were docketed before October 27, 1972, and are yet to be licensed, and thus could conceivably be covered by the deleted Subsection II.2. These plants are Watts Bar 1 and 2. All other pre-1972 plants have either been licensed or canceled. A
