SUMMARY

Tha Unit operated at 100% during March 1999 with the exception of two short downpowers. The first downpower occurred on March 19,1999, and lasted approximately one hour and 45 minutes. This downpower w s caused by unanticipated cycling of the 'B' Reactor Recirculation Flow Control Valve. As the valve cycled, rsector power reduced from 100% to 94%, at which time the FCV was locked in position. Feedback position indicition was swapped from the Radial Variable Differential Transformer (RVDT) to the Linear Variable Diffsrsntial Transformer (LVDT). The FCV was then reset and power raised back to 100%.

Tha second downpower occurred on March 31,1999, and lasted for the final three hours of March 1999. The purpose of the downpower was to perform Control Rod Drive exercising.

3. Off-Site Dose Calculation Manual Changes-Updated revision numbers, page numbers, and added a file designator identifier at the bottom of each page.

Corrected title for Section 10.2.5 in Table of Contents.

Changed date for start of oil burning to Fall of 1998 on page 10-1. ,

Revised the wording for Section 10.1.3.1.2 to reflect the method for establishing setpoints for the condenser l air ejector monitors Corrected typographical errors in the following:

. Monitor EPN on page 10-7 e Description of the distance for drinking water sampling location on page 11-6. l e Operability Requirement section on page 12-25 .

i Revised the wording for Section 10.2.4 to clarify the allocation of liquid releases from the Station.

Revised Figure 10-3 to indicate a generic symbol for the flow element and deleted obsolete EPN.

Corrected sampling locations for L-01 and L-03 on page 11-2.

Added clarifying statement for the following: .

l

. Sampling requirements for food products on page 11-7 i e Applicability statement on page 12-8 to define that the requirement is applicable only when there is flow in the system

. Action 101 on page 12-10 defining requirements if action exceeds 30 days Deleted EPNs for the Cooling Pond Blowdown Pipe Added note to bottom of table notations on page 12-15 explaining actions required if 30 day period is exceeded.

Corrected Table number designator on page 12-23 On pages 12-25,12-37, and 12-38, amended ACTION defining requirements when limits are exceeded to reference the appropriate reporting requirement in 10 CFR 50.

Added wording to Bases on page 12-27 to allow for system bypass to portable waste treatment equipment.

r .

Off-Site Dose Calculation Manual Changes-(Continued) I Deleted ". '." in front of "2" in the equation on page 12-47.

Added qualifying statements to sampling requirement for food products on page 12-54.

Changed the H-3 LLD for water on page 12-57 to 2,000 pCi/l to be consistent with the Generic Letter 89-01 requirements for environmental samples.

Added notation (7) on page 12-59 defining that an LLD of 200 pCi/l for H-3 will still be required for off site ,
